Michael McMahon, co-author of the recently published eponymous book, recounts the complex motive power story of the GSWR throughout the company’s existence from 1844 – 1924. This historic subject has never been comprehensively researched before and Michael and the team took 10 years to do it. Michael therefore covers, in depth, a huge part of early locomotive development in Ireland, mirroring the expansion and needs of GSWR operations. He unravels the convoluted loco numbering system and explains the construction, rebuilding and renewal of the large fleet (325 at the end) as it evolved over 80 years. A huge amount of new information is revealed. Hear it directly from Michael.

Please note that Jon Beaumont has had to withdraw from the April meeting. We are delighted that Michael McMahon has stepped in at short notice.


We regret that our Market planned for March 2021 has been cancelled due to Covid-19
