Thanks for the further information! (I suspect that both the Green Mountain and (parts of) the MEC would have had more need of a "serious" snowplow than the Naugatuck (Grin!))
Thanks for the picture! Questions: Where did this piece of equipment start its career? Nowadays, what with global warming and all, it's hard to imagine a railroad in Connecticut needing this serious a plow (though maybe in places where, because of the way the wind blows around the landscape, snow ac...
Skimming the article: interesting that the New York Central tried out "their" Aerotrain on the Cleveland to Chicago route: the Centra's staff, as railroad professionals, saw that the Aerotrain, with its low power and non-tilting cars, was suitable only for straight and level track.
"Look" was a fine magazine, but hardly a technical journal: doubtless the powers that were at GM were happy to get a puff piece in a mass-circulation mag! Speeds over a hundred mies per hour are all very well and good, but don't translate into very short end-to-end times unless they can be...
Hummm.... Look at the dates. The last PA (Dl-304D for the cabs, Dl-305D for the PB units) were built in 1953. The first 2400 hp Alcos, the (16-244 powered) Dl-600A, weren't built until October 1955. The Alco volume (volume 2) of Kirkland's "The Diesel Builders" cites two Alco documents, fr...
Never mind the nomenclature. Alco didn't (it seems) care very much abut model names, and different Alco documents apparently disagree. The original "Diesel Spotter's Guide" used PA-3 for the last 2250 hp PA built (the ones without the drip strip" and porthole on the sides, and with ce...
Ummm. Change the verbs in the first sentence of my previous reply to plural: SSW had four of these test B36-7: they were the first four of an order for 30 B30-7. They are described (by Marre and Withers, "The Contemporary Diesel Spotter's Guide") as "test-beds" for the B36-7. And...
I believe the SSW unit was the first B36-7, and was very much an experimental/test/demonstrator unit: I think the idea was to try out GE's last technology, which would have included Sentry and, I assume, the GTA 24. But I'm not sure. The "package" with the GTA 24 would also, I think, have ...
Observation platform on end of passenger "observation" car: not a caboose. The logo could also be read as "CB" -- I think the round letter his a C and not a G, and the order isn't obvious. Suggesting (to me) the Chicago, Burlington & Quincy railroad (someone else might know i...
So, with reference to the "RME" comparative table and the idea that something of a revolution in American steam locomotive design came with the (Lima designed) New York Central H-10 Mikado and its greater superheater area, I said "So maybe I should do some arithmetic with the figures ...
Sounds like the right period for the article I remember. I've got a poorly organized bunch of old indues of "Trains": I'll look to see if I have that one (and if I don't, will write to you to take you upon your offer -- thanks in advance!). -- Looking at the table of 4-8-2 from the 1926 &q...
Thank you for your reply, putting at USRA "Heavy" 4-8-2 into a broader context! You (and Le Massena) may be right in pointing to the USRA engine a a possible ancestor of several later types. I don't know enough about the "culture" of locomotive design offices: maybe, at this late...
W.r.t. the original Rock Island 4-8-4, you say "It was bigger, I think, than the USRA Heavy 4-8-2 boiler." Yes. The USRA heavy 4-8-2 only had 76 (and some fraction) square feet of grate, but even allowing for the difference in firebox size between a Mountain and a Northern, its boiler was ...
Allegheny Portage Railroad National Historic Site. (Thanks for the suggestion, Ex-Con 90!) It does have a website, but I've only glanced at it, not explored it yet. (It is the site I visited back n the early 1970s. I enjoyed it... Of course, the Altoona region has lots of other things for a person i...
(1) Thanks for the photo! Traction motors would be the usual 752 model used on domestic (standard gauge) units: I think I can see, at the left end of the near axle, where the gears were set a bit inboard. (Russian gauge is ??? about 80 millimetres wider than standard, so a 752 motor won't fill the w...
