The County Donegal Railways had a route of 124 miles, five termini and three junction stations. For the most part they traversed hilly and thinly-populated country and for two generations they were a busy and efficient operation. This edition adds a valuable chapter of interviews and memories of some of the surviving workers and others who had contact with the railway.

It also includes a chapter on the County Donegal Railway today (as over 50 years after closure, much can still be seen of the former network), and some additional Glover drawings of locomotive, carriage and wagon stock.
