JointedRail stuff [screenshots/renders]

Actually the FEC doesn't own ES44AC's nor ES44DC's. They did own a small fleet of SD70M-2's, which can be found on JR's Freeware section. However, they've gotten rid of those and replaced them with a fleet of ES44C4's, which are ES44AC's with only four powered axles instead of six. Only the first and third axle on each truck is powered. The ES44C4 has about the same amount of pulling power as an ES44DC, but with two less powered axles. The ES44C4's are painted in the same paint scheme that the FEC SD40-2 also found on the freeware section of JR's website. Actually, the FEC SD70M-2 and SD40-2 come together as a 2-pack for free.

So I would assume the only difference between the ES44AC and the 44C4's is the bogies, and would look the same bodywise...

That is correct. It's a small difference, but it's what separates the 'C4 from other Evos. It can be seen in this picture of BNSF ES44C4 #8122. There is a small 'rocker' above the center axle, connected to two air cylinders. This is part of a computer program developed by GE that raises and lowers the center axle on or off the track. The center axle is raised off the track when the train starts moving, which moves the weight of the locomotive that the center axle carried to the two powered axles, increasing the pulling power. Once the train is up and going, the center axle is lowered by onto the rails. I would post a picture of FEC ES44C4's, but the trucks are black, which would make it harder to see the mechanism on them.

A work of art Adam, you never cease to amaze.

Question: Did you release the covered hoppers you were working on?
