The Brewery in St James’s Gate, Dublin was founded by Arthur Guinness in 1759, one of dozens based on the pure water available from the River Liffey. Guinness outlasted and outgrew all its competitors to become one of the greatest brewing empires in the world.
Between 1868 and 1886 Guinness spent over £1 million on capital projects. As part of these developments, two rail systems were created within the expanded brewery site. I have covered these in some depth in an earlier article about the brewery railways. ….
Instrumental in much of the development of the brewery site was Samuel Geoghegan who was Engineer to the Brewery.
The article in Narrow Gauge & Industrial Railway Modelling Review is archive material, courtesy of ‘Engineering’ magazine and the Greenwich & District NGRS. It consists primarily of a transcript of an illustrated presentation by Samuel Geoghegan which was carried by ‘Engineering’ Magazine in September and October 1888. It includes detailed drawings, engravings and photographs. Back copies of the magazine are available from Roy C. Link, Cambrian Forge, Garndolbenmaen, Gwynedd, LL51 9RX.
Paul Webb’s book is an A4 no-frills publication in basic green card cover and printed on standard copier paper but it contains a wealth of illustrations and detailed text about the Brewery and the various forms of transport, road, rail and water, that served it. Well worth the £8.50 plus postage that it cost, especially knowing that any profit from the sale supports the Moseley Railway Trust.
There are also some excellent YouTube offerings which focus on the brewery and the different modes of transport it employed. …. For example:
