Is there a place to find old timetables -- meant for either passengers or, even better, trainmen? I'm looking for an early 1920's-era timetable for the Reading Phila-to-Newtown line. I'm mostly interested in the times and also meets if they are documented, and not so much the artwork. My understanding is that there were about 34 daily trains, including about 17 passenger trains, on that line in those days. Thanks very much.
