Phillax: That period you describe were the Conrail contract operation years...
April 1, 1976 to December 31, 1982 were the dates...
Silverliner Four cars delivered before April 1976 did include the PC and Reading heralds placed on the cars.
Some of the 100 series cars assigned to the RDG and the 380-399 PC cars were delivered after Conrail took
over both services in 1976 and had neither herald. All Silverliner Four cars had the round red SEPTA logo.
For some reason the Conrail herald was rarely used on any equipment in SEPTA service. I only remember
seeing one Silverliner Two car with the CR logo.
The first use of the SEPTA square logo was on the RDCs used for the "Fox Chase Rapid Transit Line" service
between Newtown and Fox Chase. After SEPTA took direct control of the Regional High Speed Lines (original
title of Regional Rail) in 1983 they placed the then-updated SEPTA logos on all RRD equipment covering up
(and not removing) the older SEPTA, PC and RDG heralds.
