As there is an interest in old maps and timetables, here is a link for the Survey of India map of railways, roads and canals dated 1911. Unlike other SOI maps of the Railways, it appears to show all (or most) stations which existed at that time. It also covers British India and Burma of that time.
You could download this from:
