So I'm just curious as to what the ex UP motor is if anyone has any info on it or what it's doing at Star. Check the link now b/c it's a reject and will disapear soon!

According to Don Strack's fantastic Utah Rails site, it's an S5-2B rebuilt from a retired KCS GP30... but boy, I see nothing GP30 there (those are Dash 2 trucks, I think - and nothing on that body looks GP30-ish0.

Here's an image of its sister.

ACWR recently completed their first slug set, 703/704. This is a similar team to a CSX ROAD MATE set. They are apparently quite pleased with the performance of this duo, and I believe may plan on doing another. I don't know if this is a candidate for the next one, or a parts source. Slugs can be used for salvaging traction motors or a few other components. BTW, here is a link of it in retired state at UP, close to what your photo is, so this will hang around for reference:


They definitely removed something from the end. I was suspecting remote control gear, but it appears there was something else there on the end that was cut away. Possibly was a sand box, based on the access port on top.

From what I've heard, I don't think there are any plans on putting it into any train service. But more of a test rack to test the locomotives that they already have.
