Fun fact. PRR steam numbers were an insane jumble.I don't know what they were doing back in the day, but they seemingly just used a random number generator when assigning numbers to locomotives.
You brought up the E7’s, which is what I was referring.
The Railwire is not your personal army.
Are you saying that the E7 locos were used in freight service after the E8 locos arrived?
The PRR used power any way they wanted, and yes I have read of re-gearing examples too.
Now for the story about the E units on trailer trains. That ill-fated caper was instituted while I was assigned to Canton Diesel Shop, which would pinpoint it as being about February 1964. With all the train-offs, there was a surplus of E units on the passenger side so sets of three were assigned to TT-1 and TT2. I managed to get in one shot of TT2 coming through Canton and a very cloudy day and the idea was scuttled before I had the opportunity to take more photographs.The reason they cancelled the act was because they flashed over several main generators in the process. Whereas the freight units all made backwards transition, the passenger units did not. What that means, in layman's terms, is that if the train was say, accelerating in notch eight and the engineman wanted to go at a slower speed without using air, on a freight unit, he merely reduced the throttle setting from notch 8 to say notch 6 and as the train slowed, the locomotive "shifted gears" (electrically of course) to compensate for the slower speed. Remember, the passenger units did NOT have dynamic brake so the freight enginemen were not accustomed to operating units without dynamic brake,So the correct method in the above circumstances using a passenger unit in freight service would be to go from Notch 8 to OFF and then bring the throttle back out to Notch 6. Doing it incorrectly resulted in the distinct possibility of the main generator flashing over, which of course necessitated a trip to Juniata for a generator change out.
I'm no Pennsy expert, but a few observations:PRR E units were originally painted DGLE, and used in passenger service. Tuscan (various schemes) came later.The E7 5880 in the picture referenced below has a coupler cover. This cover would not have been used in a unit reassigned to freight service.Early PRR E units had the 5-stripes carried over the windows (you can just make this out on the E7 5880, and its clear on the E7 5863, E7 5901 and in the E8 5799 pictures). This is an indicator of early (passenger service) units.I don't know if PRR ever regeared E units for freight service. Other railroads certainly did. However, the examples in this thread all appear to be in passenger service.
Just to be clear, Brunswick Green was applied earlier than Tuscan Red...correct?
Yes - for passenger diesels. The red started in late 1952: https://jbritton.pennsyrr.com/index.php/tpm/latest-articles-blog/111-history-of-passenger-diesel-paint-schemesFreight locos never got the "red" (as far as I know).Mark
