Modern Tramway February 1951 – New Tramcars for the Brno Tramways in 1950/51

The featured image for this article is Brno Tramways No. 131 with Trailer No. 310, which early in 1951 was newly delivered to Brno. [1: p21]

Gerald Deuce reported in February 1951 on a series of new tramcars being delivered to Brno in what is now the Czech Republic. [1: p25-26]

He writes that these tramcars:

“are uni-directional single truck motor-cars with trailers of similar design and are intended for PAYE [Pay As You Enter] operation with the entrance at the rear. All the doors except the leading set of the motor-car, are under the control of the respective conductor.

“The cars are heated by electric radiators fitted under the transverse seats, and lighted by a fluorescent tube strip along the ceiling.

“Brno is the capital of Moravia and has a population of just over 273,000. It is situated about 130 miles south-east of Prague, and is the centre of the Czechoslovak textile industry and an important tourist centre.” [1: p25]

Their ‘vital statistics’ were: ….

In this table, the first column of figures relates to the motorcar the second column of figures relates to the trailer. [1: p25]
As far as I can tell the trams introduced in 1950/51 in Brno were KPS Brno 4MT trams and the trailer is a vv4 trailer car. Deuce  does not give full details. [1: p25]

In 1950, the Královopolská strojírna plant in Brno manufactured new tram cars, including the KPS Brno 4MT2 motor tram and a vv4 trailer, which served the city. This period focused on modernizing existing infrastructure, with four-axle T-series trams and K-series cars introduced during the 1950s/60s. The KPS Brno 4MT2 tram, manufactured in 1950, was later used in the 1970s by the Technical Museum. [9]

Deuce continues:

“The tramway system is of standard gauge, the lines all rising from the railway station, near the centre of the town, with a total route mileage of about 23. The main depot and workshops are at Pisarky, approached by a long sleeper-track section. This line also serves the exhibition grounds, where there is a special four-track layout. There is an interurban line to Lisen, 5.2 miles long and nearly all on private right-of-way; most of this line is single-track with passing loops, with automatic colour-light signals.

“Services operated are as follows:

1 & 6 Pisarky – Reckovice.
2 & 8 Horno Herspice – Zidenice.
3 & 7 Obrany – Bystrc.
4 Komarov – Masarykova ctvrt.
5 Julianov – Stefanikova ctvrt.
9 Julianov – Cerna pole..
10 Nove Sady – Lisen (interurban).

“The higher number indicated against the first three services refers to a short working over the central portion of the route. Services 5 and 9 run together for most of the distance. Frequent services with trailers are operated on all routes. The through trains on the Lisen line usually consist of a motor-car and two trailers, and run at intervals varying between 15 and 40 minutes; there are additional short workings.

“There is a flat fare of 2kcs. 50h.” [1: p26]

The Brno tramway network (Czech: Tramvajová doprava v Brně, simply Tramvaje v Brně) was the first network of its kind to be put into operation in what is now known as the Czech Republic with its horse tram lines dating back to 1869. [In the 21st century], Brno is the second largest city in the Czech Republic, after Prague, and its tram network is also the second largest in the country.” [5]

At different times, three different modes of propulsion were used on the network: from 1869, horse-power was in use; from 1884, steam-power was in use; and from 1900 electric trams were introduced. [5]

Brno hosts a tram parade in June each year. The three images below come from that parade: ….

These next paragraphs come from a webpage written in 1998/99 by Richard Bilek from the Czech Republic, who died in 2001 (R.I.P.). Translated from Czech, that have in places been paraphrased to read more easily. They are a ‘snapshot’ of the tramway network in Brno in 1998/1999 and a potted history of developments from the 1950s to the late 1990s. [2]

“In 1951, Brno had 62 km of network. In 1948, the last two-axle tramcars from Zbrojovka Zidenice were delivered. In the 50s, the city renewed their tramcars with new progressive tramcars of class T2. 94 tramcars of this type were delivered till 1961. No T1 type tramcars were purchased by the city.

“In 1963 new tramcars of T3 arrived. The city wanted tramcars with bigger capacity. Tatra Works developed articulated tramways of type K2 in the mid of 60s. First prototypes were tested here in 1965, and between 1966 and 1977, the City purchased 132 tramcars of this type, so they operated the largest fleet of K2 tramcars in the Czech Republic. These tramcars were still most typical for Brno at the end of the 20th century.

“All Czech cities except Brno at the end of 60s shortened their network at the end of the 1960s. Brno was the only city with uninterruptable expansion of track after WW2 through until the turn of the 21st century. New housing estates in Brno also were connected with the tramway and later, with trolleybuses. The last major expansion, a new line, was opened in 1989, a further short connection line was opened in 1994. An additional 2.2 km was under construction  in 1998/1999. The city purchased new KT8D5 tramcars at the turn of the 21st century, 28 cars entered service. Further renewals were also planned – T6B5 type. and low-floor tramways of RT6N1 type.

“The city was operating the following tramcars just prior to the turn of the 21st century:

1470+1462 Last units of T2 tramcars of T2 type. These two vehicles were due to be scrapped in 1998.
1495..1668 Tramcars of T3 or T3SUCS. Mostly in service
1001..1132 Articulated tramways of K2. 126 still in service
1701..1728 KT8D5 Tramcars. One withdrawn after an accident
1201..1220 New T6B5 tramcars, delivered 1995 and 1996
1729..1735 KT8 tramcars with low-floor mid section
1801-1804 RT6 low floor tramcars

“The city also sought to renew these old tramcars:

“Tramcar T3 no.1615 was rebuilt in 1993-1994 to new type T3MB with new body, renewed electricity, etc. There was a hope to rebuild approx. 70 tramcars to this state, but only 11 had been renewed by the end of 1997.

“Also, K2 tramcars were intended for renewal in this way. First prototype was rebuilt in Pars DMN Sumperk works (small city approx. 120 km norhtern from Brno) and was placed in service in Brno. An additional batch of 6 similar tramcars was renewed later.

“There were plans to order new KT8 tramcars (for a new line to Lisen). They were due to be delivered with a low-floor middle section in 1998/1999.” [2]

The Modern Tram Network

As we have already noted, Brno is the second largest city in the Czech Republic, after Prague, and its tram network is also the second largest in the country.

The urbanrail.net webpage has a more detailed map and plenty of images of trams in service on the network. [4]

The Brno tram system comprises 12 lines, with a total operational track length of 139 kilometres (86 miles) and a total route length of 70.4 kilometres (43.7 miles). The lines not only serve the urban area, but also lead to the neighboring town of Modřice located south of Brno. Before construction began on the final leg of the extension in 2008, the entire network was made up of 69.7 km of track. [5][9]

Early Monorail Proposals in Russia

Ivan Kirillovich Elmanov (Russian: Иван Кириллович Эльманов) was a Russian inventor. During 1820, in Myachkovo, near Moscow, he built a type of monorail described as a road on pillars. [3] The single rail was made of timber balks resting above the pillars. The wheels were set on this wooden rail, while the horse-drawn carriage had a sled on its top. [3] This construction is considered to be the first known monorail in the world. [5][6] The horse-drawn carriages travelled on an elevated track. One project envisaged using them to transport salt on Crimea. [9]

Russia was a pioneer in the design and construction of monorails, from early horse-drawn models to later electrical and magnetic levitation systems. [2] Sadly, Elmanov could not find investors to fund for his project and stopped working on the monorail. In 1821, Henry Palmer patented his own (similar) monorail design in the UK. [2][3]

On Elmanov’s monorail railway, the wagon rolled on a special rail on wheels mounted on a frame, so the vehicles had no wheels but virtually contained the rail. [9]

Later examples of early (pre-1900) Russian monorail proposals include:

  • In 1836, Prince Beloselsky-Belozersky [8] proposed another monorail design which contained two rows of wheels on mounted on a pillar structure; [2][3]
  • In 1872, a monorail designed by Lyarsky was shown at the Polytechnic Exhibition in Moscow; [2][9] (This was 4 years before the construction of a steam-powered monorail for the United States Centennial Exposition in the USA); [3]
  • In 1874, Alexei Khludov [10] constructed a monorail for transporting wood; [2][9]
  • In late 1899, Russian engineer Ippolit Romanov built a prototype of an electric monorail in Odessa, modern-day Ukraine. “In 1897, he presented a functional model of his monorail at the meeting of Russian technological society. This idea was approved by the society, and an experimental electric monorail was built in 1899. In 1900, Empress Maria Fedorovna approved the building of an 0.2 kilometres (0.12 mi) long electric monorail in Gatchina. The monorail was tested on 25th June 1900. The monorail carriage … moved at a speed of 15 kilometres per hour (9.3 mph).” [2] “The cars weighing 1600 kg were made like the trams of that time and were suspended on a truss metal overpass at a height of at least 750 mm from the ground. Based on the published photographs, it can be assumed that the overpass was temporary and rested on long beams laid on the ground. … The car bogies were two-axle, with one running wheel with a diameter of 120 mm. Each bogie also had two pairs of horizontal guides and stabilizing wheels. Two motors with a capacity of 6 kW each operated on direct current with a voltage of 100 V. The electric drive control system provided for the possibility of regenerative braking. Power was supplied from a contact wire on the beam, the beam itself served as a second wire. … On 25th June 1900 (according to V. Nikolaev – 29th June), the monorail was tested. During the tests, the monorail moved with a load of up to 3200 kg (i.e. 2 times the tare weight of the carriage), with this load the speed was 15 km/h. It was noted that the carriage moved smoothly, without jerks and jolts. … According to the journal “Zheleznodorozhnoe Delo” No. 38,1900, the Romanov system … had advantages over foreign designs known at that time. The asymmetrical suspension scheme on an open beam, on the one hand, allowed this beam to be made fairly light and cheap, and on the other hand, allowed the bogies and drive to be made reliable and easy to maintain. … Romanov also put forward the idea of automatic driving of the monorail. In the magazine “Niva” No. 30, 1900 in an article about this monorail it was written: “Since the movement is produced by electrical energy transmitted along a copper wire along the entire route, then this same energy can be used to automatically divide the entire route into sections on which only one train can be at a time. Each train can approach the one in front no more than a certain distance, for example, about 1.5-2 miles. When the distance between trains decreases to this limit, then the train behind stops, although, of course, if necessary, a special device can bring the trains closer to each other to the desired distance. Acceleration or deceleration can be done automatically, so that the inattention or carelessness of the driver is corrected independently of him.” [3]

A First, Short-lived, Horse-powered ‘Railway’ in Hungary.

The first Hungarian ‘railway line’ was completed nearly 20 years before the first steam-powered railway in Hungary (which was opened in 1846) on 15th August 1827, and ran from Pest to Kőbánya. [1]

It was one of the early horse-drawn ‘railways’ but was definitely atypical in form!!

The track of the ‘floating railway’/’suspension Railway’ on an engraving by János Hofbauer. [1][2]

That railway “ran on a wooden structure running at an average height of one and a half to two metres above the ground, where the wooden beams were held by densely placed wooden posts. The wheels ran on very closely spaced rails on top of the beams, and the carriages hung down on either side of the entire structure, therefore floating, i.e. the design was very similar to a monorail.” [1]

The strange, complicated structure was not a Hungarian invention, it was patented by an Englishman, namely Henry Palmer.” [1][4]

Palmer made a patent application in 1821 for an elevated single rail supported on a series of pillars in an ordinary distance of ten feet, inserted into conical apertures in the ground, with carriages suspended on both sides, hanging on two wheels the one placed before the other. A horse is connected to the carriage with a towing rope, proceeding on one side of the rail on a towing path.” [4]

There was an earlier monorail in Russia, [5] of which Palmer was unaware. By 1823, George Smart had set up a trial version of Palmer’s monorail. [6]

Palmer wrote in the study presenting his system: “the charge of carrying the raw material to the manufacturing district, and the manufactured article to the market, forming no small proportion of its price to the consumer.[…] The leading problem in our present subject is, to convey any given quantity of weight between two points at the least possible expense.[…] In order to retain a perfectly smooth and hard surface, unencumbered with extraneous obstacles to which the rails near the ground are exposed, it appeared desirable to elevate the surface from the reach of those obstacles and at the same time be released from the impediments occasioned by snows in the winter season.” [7]

Palmer’s Monorail – The earliest patent for a vehicle designed to run on a single rail can be traced to UK patent No 4618 dated 22nd November 1821. Palmer described it as ‘a single line of rail, supported at such height from the ground as to allow the centre of gravity of the carriages to be below the upper surface of the rail’. The vehicles straddled the rail, rather like a pair of pannier baskets on a mule. Propulsion was by horse. A line was built in 1824 in the Deptford Dockyard in London, and in 1825, another line was built in Cheshunt, Hertfordshire. Dubbed the Cheshunt Railway, this line made history as it was the world’s first passenger-carrying monorail, and the first railway line to open in Hertfordshire. In 1826, a company was formed to construct a line between Barmen and Elberfeld in Germany, but construction never started, © Nekosuki600, and licenced for reuse under a Creative Commons Licence (CC BY-SA 3.0). [8]

In the 1820s, this system seemed to be very advantageous, since it was not necessary to raise embankments for its construction, the track could be created with relatively little earthwork, only a suitable amount of wood was needed. Such a railway was experimented with in several places in Europe, and Baden salt mine manager János Gáspár Bodmer jointly applied for a patent with the Austrian company Bollinger & Co. for the construction of a Hungarian network of more than 900 kilometers, which would have connected Pest with Debrecen and Fiume, for example. The costs were correspondingly high, the price of the entire network was set at two million forints.” [1]

Palatine Joseph liked the idea. “Archduke Joseph Anton of Austria … was the 103rd and penultimate Palatine of Hungary who served for over fifty years from 1796 to 1847, after a period as governor in 1795.” [3]

Before the entrepreneurs could get a license covering the entire country, the Palatine first wanted a test track that led from Pest to Kőbánya. “The Pest-Kőbánya route was ideal because the stones and bricks for the constructions in Pest were transported from Kőbánya, and by joining this stone transport business, the railway would have made a profit even on this short section of less than 7 and a half kilometres, according to the plans.” [2]

Work on the 7.6 kilometre railway section began in May 1827. The company issued shares, a total of 513 shares were sold, among the shareholders were the palatine himself, György Sina, one of the richest men in the empire, as well as the banker Móric Ulmann and István Széchenyi. However, there was not enough money to use hardwood, so they built the course out of pine. The rapid work was hampered by the lack of manpower, so the palatine also ordered the military, but an additional problem was that one of the company partners and also the construction manager, János Bodmer, died unexpectedly in the early summer of 1827.” [1]

The 1,372-pole line from Pest to Kőbánya was finally completed on 15th August 1827. Its main purpose was to supply Pest with building materials, so it branched off at Kőbánya, one end point was at the Kauser quarry, and the other branch was at the Lechner brick kiln. To facilitate stone transport, the line [was] slightly inclined towards Pest.” [1]

A drawing of the floating/suspension railway (Béla Czére: A pest-kőbányai próbavasút története [The history of the Pest-Kőbánya trial railway], Közlekedéstudományi Szemle, 1957. No. 7-8). [1]

The ceremonial opening took place on 20th August 1827, attended by the Palatine himself and his entire family, who travelled from Pest to Kőbánya on the new railway. The 25th August 1827 issue of Hazai’s Külföldi Tudósítások, commented:

His High Duchy with his family, and the Deputation, led by Honourable Baron József Venkheim Főispán of Arad, at the city’s new Kőbánya, got on the carriages used for sitting, decorated with two flags with Hungarian colours flying in front of it, and all the way to the Kerepesi line, pulled by a horse, he arrived.” [2]

Palatine Joseph observed the return journey on which “a horse pulled 68 soldiers and a load of 148 Viennese quintal (that is, almost 8.3 tons), and later another train was started, and it was loaded with a total of 27 tons of stone, wool, and 40 barrels of wine. The journey time was approximately 1 hour.” [1]

The investors of the railway line leading from Pest, today’s Baross Square, to Kőbánya, naturally hoped for profit and the right to cover the entire country with their railway line later. Illés Aladár Edvi, in his study of Pest-Kőbánya Trial Railway (issue 7 of 1895 of the Magyar Mérnök és Építész-Egylet bulletin) cites the call made by János Bodmer, which he wrote to the hopeful shareholders:

In Hungary, one of the most important points to be connected would be the one that would connect Pest, the centre of the country, with Szolnok by road, because goods coming from Poland and the Russian Empire could arrive here on Tisza or the newly built road in Ungvár county; the noble wines of Hegyalja, the linen of Upper Hungary, all of these can be transported to the world market quickly and cheaply from here.” [2]

The business seemed to be successful, but problems soon appeared. On the one hand, there were not enough cars, i.e. not enough trains could run for the company to generate a profit. Of the existing 11 cars, usually only a maximum of 8 could be used at the same time, the rest had to be repaired, while three times as many, i.e. 24, were supposed to be running constantly, so the planned two trains per day could not always be started.” [1]

In addition, softwood rather than hardwood was used in the construction in order to save money. Hardwood was expensive and difficult to source at the time of construction. This led, however, to high maintenance costs and problems with deformation under load and natural drying of the timber meant that screws loosened and fell out. [1][2]

The wheels were above the cars. “The four wheels – 2 on each side – very close to each other rolled on the iron bands laid on the horizontal beams. Loads or passengers were accommodated in open structures hanging from the sides. The whole thing was drawn by horses, which of course walked on the ground. The idea was not completely unviable, according to reports from the time, a workhorse easily towed a 6-car, loaded assembly, which – converted to SI units – was nearly 14 tons including the weight of the cars.” [2]

A part of the track and a 2/3 scale reconstruction of the cars at the 2010-2012 exhibition “A hídember gépei” [“The Bridgeman’s Machines”] of the Museum of Transport (Photo: Hungarian Museum of Science, Technology and Transport). [1][2]

The railway could not “run in strong winds, because the structure had a significant defect, which could actually have been easily rectified. Since there were only wheels at the top, four per car, which were located quite close to each other, the cars hanging over the sides were rocked by the wind. This could have been avoided if the carriages were equipped with horizontal wheels that roll on the sides of the beams supporting the track and thus prevent swaying, but neither the freight nor the passenger carriages had such wheels.” [1]

As early as the spring of 1828, it became clear that the entire line should be rebuilt and replaced with hardwood, and new, horizontal wheels should be placed in the cars, which would reduce the swaying.” [2]

The venture also carried high finance costs. The project exceeded the 20,000 HUF budget, coming in at 31,000 HUF. New shares were issued, but not enough money came in. As a result, the Company owed nearly 5,000 HUF to master carpenter József Spiegel, the head of the construction, who took over the management of the construction after Bodmer’s unexpected death in 1827. [2]

No account appears to have been taken of the state of the market at the time. “The company would have been successful if it had continuously delivered building materials to Pest. However, it would have been necessary to successfully break into an already well-established … market, which would have been possible if the work was taken away from the competitors, who used to carry out the deliveries with carts, or … construction work in Pest … accelerated in such a way that … excess capacity” was required. [2]

The market did not grow and there was no need for additional capacity. The carriers who had been transporting building materials until then were not happy about the competition and formed a cartel to lower their prices, i.e. it was cheaper to transport by cart than by rail.

At the shareholders’ meeting held on 20th March 1828, the situation was quite hopeless. The railway was already struggling with a debt amounting to 4,339 HUF 35 kreuzer, and it did not generate enough income to start making a profit. To hope for a profit, major improvements would have been necessary, for example, new cars would have had to be purchased. For the continued operation of the railway, and to have enough money for purchases, each shareholder should have had to pay an additional 15 HUF.” [2] This they were not willing to do. so the company ceased operations on 20th March 1828, i.e. after 7 months. The line was dismantled, the timber was sold for firewood, but there were beams that were used at the Chain Bridge. [1][2]

From the point of view of Pest, the suspension railway was important for several reasons. On the one hand, this investment also confirmed what was stated in law 10 years later, that Pest and Buda are the country’s transport hub. The railway was based on the future hope that Pest [would face] development, not only in the field of construction but also in the field of industrial plants, which [would] require a large increase in land transport [capacity]. It is no coincidence that the railway was a trial section of a line extending to the Tisza and beyond to Debrecen – that is, from where it was not possible to transport by ship. … However, the railway was about 10 years ahead of its time. Only one public railway line operated in one place in the world, England.” [2]
