It's not, I guess, REALLY my favorite, but what about the 50-ton end-cab switcher? The one that looks like the runt from a litter of 70-tonners. I grew up in New York City, so there's a place for it in my heart! The New York Subway system has a fleet of them. Some have special exhaust-processing equ...

GE built two different 5000 hp twin-engine diesels. The first is the one Dutch Railnut describes: (16-cylinder) engines as in the U25B, built basically for UP (SP took three as a sample) in about 1963. This one had eight axles: four standard two-axle trucks (as on U25B), two on a span bolste at each...

(i) I worried, after posting, about the assumption that the change to an air-cooled compressor is what had allowed the abolition of the (Dash-7 style) step in the hood side on "Enhanced" Dash-8. My recollection is that the change in compressor was announced at about that time, and that the...

Actually, there were two different models... The original B32-8 were three test/demonstrator units, GE-owned but painted in BN green, built in 1984 (since retired and I think scrapped). These had the original Dash-8 styling: curved cab roof, very "busy" long hood appearance (with step in t...

The truck-frame casting was one of the components GE bought from outside suppliers. My impression is that they patronized both GSC and Adirondack in the 1960s; I **think** they got more from Adirondack in the Dash-7 period (late 1970s), but I could be wrong about this. Note that Adirondack, at least...

Thank you! (Sorry for not replying earlier.) Well, I'm learning things! I am surprised that the holes are jacking points, but apparently they are (at least on SOU units). (The person who sounded more confident about their being jacking points on the "LocoNotes" forum also referred specific...

These are GE locomotives, and -- essentially -- the same model. Model designations have become totally unsystematic (GE's insistence on writing "C40-8" as "Dash-8 40C" in the late 1980s didn't help), but the form I used in the heading is a reasonable guess: "AC" prefix ...

What you say makes sense to me, and I was very surprised that two (knowledgeable SOUNDING) people wrote to "LocoNotes" with the lifting point suggestion.... My two thirds of a nickel is...I'm interested in railroads, but have no first-hand experience working on them. So I can only tell you...

No, the holes show up black: the photo I linked to is of a yellow U23B, and the dark holes are especially visible against the yellow background. So far two people have written in to the "LocoNotes" forum to say they are probably jacking points for lifting the locomotive, and one to say he ...

I asked the same question on the "LocoNotes" forum and got a couple of answers, one guessing and one asserting confidently that, at least on SOU GE units, these openings were lifting notches: where to put the hooks if you want to lift the unit off its trucks with a shop crane.

As I recall, it was a clearance problem atn one particular coal loader at a mine served by ATSF. The "gull wing" (some railfan magazine published a full-page photo of a train led by a new Warbonnet C40-8W -- ?C41-8W? -- when ATSF ordered the first units with this option, and the accompanyi...

Photos of U-series diesels of the ATSR and Southern show dark rectangles-- I assume holes-- in the side frames just inboard (i.e. further from end of locomotive) of the stepwell at each end. (It shows up nicely on a light yellow U23B: photo, coutesy of "Northeast Rails," at http://www.rail...
