I could not find a photo of an PRR E7 in green only tuscan as all passenger locos were tuscan.
Might wanna look
liiiiiiittle bit harder there Whitepass...
All E7s and the first order of E8s were delivered in Dark Green Locomotive Enamel (DGLE), which was the standard dark dark,
dark, green paint for the PRR. Allegedly even their steam locomotives were painted in DGLE, but it usually appeared more black than green. You'll also notice that the keystones on the nose have numbers in lieu of the interlocked PRR lettering as well.
If you notice the pilots on those units, the first batch of E7s that were delivered arrived with faulty coupler door assemblies. The coupler did not extend out far enough, which left little room for crews to get to the air hoses. As a result, for a short period units with the original squared off doors could be seen with one door removed (5853 in Dan's post interestingly enough is shown during this period, although why the units are without trainphone antennae is beyond me). Although EMD redesigned a replacement, PRR fabricated their own massive huge doors (aptly dubbed "Frankenstein" pilots) at Altoona for this first batch of units. These doors did not slide outwards like the EMD design, but rather were hinged "clamshell" doors (5843 has them in the open position in this post). The second batch, from 1948 onwards, were delivered with standard later EMD coupler doors on the pilots, as well as lift rings on the nose. By 1952, all units were retrofitted with lift rings (among other modifications). All units were delivered with small numberboards, however the PRR modified them at Altoona around 1955, giving them large homebuilt numberboards up front. The coupler doors were also removed at this time as well. Also note the single forward facing single chime air horn mounted over the engineer's side on top of the cab. None of the E7s that I'm aware of were delivered with a rear facing one, however during rebuilds the units received a variety of multi-chime horns later in their lives.
The gold leaf five stripe and DGLE scheme was standard on all passenger power (EP-20s [E7s], E8s, PAs, BP-60s, BP20s) from 1945 until 1952-1953. While a few E8s did receive a Tuscan and gold leaf scheme in 1952, very shortly after delivery the motive power department changed the gold color to buff gold, a less expensive substitute.
I'll leave you with a totally only Tuscan set of photos of PRR passenger power from a five minute google search.
PRR photo op! What a cool shot. The PRR public relations guy really earned his money getting all those engines lined up just perfectly.
Also thanks Heinrich! Always glad to help the PRR PR guy prove his worth!
