Bus and transit timetables are an often overlooked part of the timetable collecting hobby. Many intercity bus companies can
trace their origins back to their days as subsidiaries of railroad companies and many transit timetables are based in part
on former streetcar issues. Some urban transit systems, such as San Francisco MUNI, Philadelphia's SEPTA have retained a number
of streetcar and light rail lines, while others, such as Buffalo,NY, Sacramento,CA, St. Louis, MO, and Salt Lake City, to
name afew, have built light rail systems from scratch. Many of the timetables issued by these properties are issued in the
form of pocket folders. San Francisco, however, issues a system wide schedule book. The next several pages will deal with
form varieties and timetable books in some details.
