A few more pics from what I use for research.
1) the PRR 2’BB2′ four-cylinder steam locomotive shown before, but now with the mentioned electric classification light clusters either side of the nose next to the head light. This one has an extra fog light fitted, incidentally. In dense fog people on the ground turned out to be less able to see the mile-high fitted headlight, bit of a risk along the line and in yards. The machine is pictured coming down the famous horseshoe curve, an area that PRR would have liked to electrify but never could raise the funds for. Anyone explains to me the economy of this machine over the DE locomotives in the next picture.
2) The original Co’Co’ diesel shark nose passenger locomotive design of a Baldwin/Westinghouse/PRR ABA set in ex-factory condition. Notice the handrails on top of the machine, typical for PRR practice: hardly anyone else had that. Strangely enough the head light and classification light clusters on the PRR diesel sharks never became what PRR fitted on other traction. The forward shining marker lights are fitted in the main body and the numbers sit in the side.
3) E3b Tri-Bo’ 4995 AC to DC test electric with the PRR classification light clusters as mentioned. Notice that the doors near the coupler, mentioned in another email, have been taken off. Although she is in very good external condition I have a feeling that she’s dumped, awaiting her fate in this picture. Incidentally, notice that safety flap next to the front pantograph on top of the ladder.
4) Baldwin shark nose type of diesel electric traction for PRR main competitor on the New York to Chicago run, New York Central, for what looks like a Talgo type of lightweight train. Fitted with the PRR classification light cluster; see what I mean about that vexing lack of consistency that would enable using such features to determine issues?5) Another Baldwin demonstrator with an interpretation of the shark nose design, especially the windscreens give the Baldwin/PRR design studio away even if the machine does not belong there. Classification lights as per Baldwin/Westinghouse/PRR standard but no roof-rails. Am still looking where this is, can’t read what’s on the building or on the locomotive.
