Author: SCUfoamer

A couple of you have reached out asking about the pair of T4 Geeps that switch the local jobs out of Warm Springs Yard. Heres a  3-pack of the couple.

Electro Motive model designation is EMD24B which UPRR is classing as GP22T4 (note on the 5th photo; posted here by SCUFoamer, the "GP22T4" class designation stenciled on the cab). Core units are EMD GP38-2’s. The rebuilt/repowered units are each powered by a Tier 4 compliant V-12 CATERPILLAR 3512D HD Industrial Diesel prime mover with a Kato alternator, rebuilt D78 traction motors, are rated at 2,000 hp and use urea. The conversions are done by Progress Rail; a subsidiary of Caterpillar, Inc, at their facility in Patterson,GA.

Urea is used for the exhaust after-treatment system.  They are fueled be good old-fashioned low sulfur diesel fuel.

Harbor Hog -

Thanks for spotting my typo, and giving me the "heads up" that I messed up the copy-and-paste job LOL. I wanted to post: "...powered by a Tier 4 compliant V-12 CATERPILLAR 3512D HD Industrial Diesel prime mover with a Kato alternator, rebuilt D78 traction motors, are rated at 2,000 hp and use urea".

Great catch and coverage,

Thanks! All images except #3 are taken along the Vasona Branch. Image number three is an industrial spur in South Gilroy.

That 3512 with Kato alternator is a rugged combination.  They should get good performance with that duo.

Progress Rail website says its constructed with a new crashworthy underframe, cab and fuel tank. And refurbished Trucks and traction motors, Were the UP ones actually put on GP frames?

Pshaww, the 3500s in locomotives have a very checkered past, hope these work better than the last 20 or so.

Cat/Kato combinations have NEVER found any success in the railroad market. What makes this one different?
