Description

In 1953, General Electric dissolved its locomotive-building partnership with the American Locomotive Company. A year later, GE produced an A-B-B-A set of cab units under the guise of export units, which were really testbeds for the North American market. The original set consisted of an A-B set with 8-cylinder engines outputting 1200 HP each (UM12B) and a second A-B set with 12-cylinder engines at 1800 HP each (UM18B). They first tested on the Erie as 750A-D, receiving various modifications over time before finally being upgraded to 16-cylinder engines at 2000 HP each prior to sale to Union Pacific in 1959 as 620, 620B, 621, and 621B. UP ran the units until 1963, when they were traded in for U50s. The information that GE learned during tests allowed them to produce a very solid product when they introduced the U25B, and strongly influenced the FDL prime mover that they continued to use for decades.

    Nice to have a cab unit that is not an “F” unit. This is a great looking 4 unit set. The corrugations on the sides are very convincingly rendered as are the kick plates on the top two steps. Trucks also look good to me and I’m quite fond of the side by side twin headlights. Overall appearance is excellent and also appears to be fairly accurate from the very few decent photos I’ve managed to source. The side cab doors open as do the drop lights on both the cab side and on the doors themselves. Air deflectors are adjustable and the horn is one of the deepest tones I’ve ever heard on a train. There are class lights and number board lights too.

    If you are looking for a detailed cab then this may not be the model for you as it uses the same very basic cab as the freeware “F” units. These were the only four experimental units built so where would accurate cab appearance be found now days? One other issue which may or may not trouble you depending on your preferences is that no driver figure appears in the cab when the train is in use, although, that said, with the cab doors and windows closed this isn’t very obvious.

    These units drive appropriately for their power and period of manufacture. The engines build and lose revs. a little more slowly than modern units as they should and they sound good to me. This is an unusual and very likeable model.

    Got them in a sale and very pleased with them.

    As previously said freeware “F” units cab, no driver figure appears in the cab the fist Np for me then i rarely drive in cab, but no fig A little disappointed, most bought this to have something similar to the “F” unit that is not 100 years old in trainz, and more like 2019 trainz, have been looking but not finding anything, so this was the closest I could come 🙂
