Following the initial Septa's Reading Division transition to Conrail-contracted commuter operations in April, 1976, three versions of the "Bethlehem-Quakertown to Philadelphia" timetable were printed for 5-23-1976, 9-7-1976, and 10-29-1976.
For the initial transition, the Reading Lines diamond was replaced with the new "ConRail" logo, with lines above and below, and "Reading Division" was added alongside the logo. The 9-7-1976 version showed the addition of the wheels on track logo with "CONRAIL" alongside.
No changes were made for the third CONRAIL version for 10-31-1976 shown here.
A heavily revised October 29, 1978 version of the table shows the CONRAIL logo removed, and "Operated by Conrail under contract with Southeastern Pennsylvania Transportation Authority" added at the bottom.
The blue Bethlehem colors were changed to green, and Septa's stylized version of commuter power was added.
The cartoon appears to represent a combination of an MU and a cab unit which seemed to fit the Reading Division that operated Silverliners and FP7's.
However, Septa also included this cartoon on ex-PC Philadelphia commuter line timetables that only operated MU's.
