Hello
A book which will be useful, from the Official History series is "Transportation on the Western Front". In its 1937 edition it is probably pretty scarce, but the IWM / Battery Press reprint of 1992, ISBN 0898391792 should be not so difficult to find. There is a box of 14 maps to accompany the volume and 17 sketch maps in the book itself.
Of course not just railways are covered but certainly there are sections of the book with deal with light railways.
I hope this will be useful
