[PRR-talk] U25C/E44 and brethren

[craigmiller4 at comcast.net]

I believe the U25C & E44 trucks were the same, while the ALCO trucks were a different design.

Other ALCO trucks (RSD-7, RSD-15 etc) I believe are the same as the Century series 6-axle trucks (except of course for the Hi-adhesion C630's on RDG & C636's on PC)

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.
