Hi,
I am looking for plans to the U25B and the U25C.
I am interested in a couple of points such as:
1) is the frame longer on the u25c than the u25b?
2) can a U25b have three axle trucks under it with just the alteration to the fuel tank?
Thanks.

yes.



real locomotive or model?
technically, either would be yes..
but it would be a lot easier on a model, and you wont see it done on a real engine.

and.. the "B" in U25B stands for 4-axle trucks,
and the "C" in U25C stands for 6-axle trucks..
so if you put 6-axle trucks under a U25B its no longer a U25B..
(it wouldn't be a U25C either..it would be a mutant.)

some railroad in Brazil has re-trucked a bunch of GE's..with a BB-BB arrangment..but for the most part, American railroads dont re-truck locomotives in this way.

Scot,

Thanks for your response

I am scratch building a PRR E44a electric (in HO).

The trucks for the E44 seem to be the same as those that are under the U25C. Bowser/Stewart has a U25b available.

I am interested in finding plans to see what the differences are between the U25C and the U25b. I assume they both use the same hoods and hood lengths and door patterns.

Although the U25c is shorter than the E44, a reasonable facsimile was made using two AHM U25Cs in a 1966 RMC article.

If the difference between the 4-axle and the 6-axle U25 is basically platform length and trucks, I might look into making a U25C starting with the Bowser U25B.

Why don't you start with one of those Bachmann Spectrum E-33 locomotives? These have been out for a few years, so I imagine you'll be able to find one on eBay or similar places cheaply.

Seems like you'd be a lot closer to having an E-44.

At the risk of turning this forum into a modeler's forum, I second the E33 motion. As it turns out, the frames and trucks of the E33 and E44 are identical, though not necessarily the stuff under the frame and between the trucks......

Hi,

Thanks so much for your response.



This was discussed in depth over on the Yahoo PRR Modeler's forum and the E33 is so different from the E44 that the conclusion was basically buy the E33, remove motor and gears, throw away the rest.

If you want the details, you can visit the Yahoo PRR Modeler's forum.

I did review my Second Diesel Spotter's Guide Update and the trucks do appear to be the same between the two.

Thanks once again. The response is appreciated and you did not know the history.

From PRR Modeling group:

2. While we're on the subject, how different were early U25C trucks
from those that appeared on the VGN/NH/PC E33 units? The E33's and
E44/E44a's put on quite a show out of Enola in the Seventies.



The U25C trucks were derivative from the ALCo Tri-mount (I believe
that is the arrangement of the trademark) trucks used on various RSD
and later models. The E33/E44 trucks were a beefier upgrade
(reflecting a larger wheel size?). The visible change is in the depth
of the outside equalizer through the several generations. The C
trucks of the U25C and the E33/E44 are quite different from those
used on GE's New Haven EP-5 and UP U50C, which latter two have
trucks which are similar to, but themselves different from, each
other.

When looking at locomotives, first check the feet.

No luck on blueprints, but I do have a GE operator's manual for the PRR E44 in my laptop bag now, "checked out" from the Md. Rail Heritage Library in Baltimore, which includes a fold-out scale diagram.

I have the flatbed scanner at the ready............ give me an e-mail address off-forum.
