This question may be better answered in the Reading Company forum in the Fallen Flags section
because these Blueliner MU cars were rebuilt and renumbered in the mid 1960s before SEPTA was
created under a PSIC (Passenger Service Improvement Company) contract with the City of Philadelphia...
I recall that a limited number of these MU cars - I recall there being nine - were rebuilt with air
conditioning and what I would like to know why more of these cars were not rebuilt with this
option - was it a experiment of sorts or was the added PSIC funding not there then?
Some of these rebuilt cars served the former RDG MU routes for up to 25 years into the SEPTA
era and was a good move to improve service during the 1960s decade...
