This page provides PDF scans of historic transit maps showing transit information ranging from 1869 to nearly present. Unless otherwise shown, these maps were scanned in from old transit publications and maps published by either Pittsburgh Railways Company or Port Authority of Allegheny County. The list below arranges the maps from oldest to most recent. Some maps have two sides, but they are scanned separately due to large file sizes (mostly 1-3 MB, one map is 7MB)
Enjoy your walk down memory lane!
