By popular request, this fourth volume in our acclaimed 'Irish Railway Photographers' series looks at the operations and rolling stock of Northern Ireland Railways in the period 1975 to 2005. In this, his first book, Sam Somerville takes us on a trip on the Province's rail network using his Rail Runabout 'rambler' ticket. We visit Londonderry, Castlerock and Portrush before heading south to the Larne and Bangor lines. The former GNR(I) Antrim branch from Lisburn is visited on our journey from Belfast to Dundalk via Portadown. For fans of NIR diesel trains this book is a must, with 60+ photographs of MEDs, MPDs, 70 class, 80 class and 450 class DEMUs all in a variety of liveries, Hunslet, Metro-Vick and General Motors locomotives and a new CAF C3K railcar. Even the odd CIE engine puts in an appearance on freight and weedkilling trains.
