[PRCo] interesting

The streetcar network PAT inherited from PRCo, quite literally, looked a 
mess but was still very viable in terms of ridership. As was mentioned 
in Part 1 of this history, PAT very much wanted to dispose of the rail 
system due to it's dilapidated condition. PAT did, however, repaint some 
of the better condition trolleys into it's gray/red/white livery along 
with a minor reconditioning of the car itself. Some rail to bus 
replacements were done in one stage while others, such as the East End 
routes, used weekend bus substitution to get the trolley riders used to 
the buses. While the lines that went would have been cut anyway, some 
lines such as lines that used the 6th, 7th and 9th Street Bridges had to 
be eliminated for urban redevelopment. By 1970, it was decided to retain 
a portion of the existing South Hills trolley routes that were mostly on 
private right of ways and a more comprehensive car and route 
rehabilitation was initiated. The 35 Library line was the line to be 
spared as the 36 Drake and 42/38 Mt. Lebanon - Beechview line would have 
Skybus running over most of it's route.
