Even though the acquisition of PRCo took place effective 12:01 am on 
March 1, 1964, any PRCo bus or streetcar on route at that time was still 
under PRCo control. Even when PAT's first bus started out of the garage, 
there were still some buses and streetcars out on the road that were 
still under PRCo ownership which were sent out prior to 12:01 am running 
with it's sister units that were under PAT control.
