That was also the same truck that delivered D&M #10 from home rails to Project 1225/SRI... and from SRI to SMRS.

You may have noticed the tight fit in the above picture. See also:

Gamma is way up so you can see the clearance.

Seems like that truck is made for GE 44's. Its bed length is 29'2". The other end is a straight vertical, hence you must remove that end's pilot, coupler and pocket, and this end's pilot as you can see here.

(and by the way, when the unit arrived, SMRS crews refitted both couplers, pocket and pilots with an ease and efficiency equal to WRM's crews, except with fewer tools and outdoor conditions! It helped that member Chuck Fannin was a rigger by profession, normally accustomed to extricating derailed hot metal bottles from under oxygen lines.)

The same truck may have also moved the GE 44 in the background, WM #75 which awaits stenciling.

Generally one does not want to move a GE 44 by rail (except on flatcar) because the units have delicate "high speed" motors with a double gear reduction yielding a 35 mph max speed.

One minor correction here; 44 tonners do not have traction motor blowers (nor do EMD SW-1s, for that matter). The rest of the differences outlined are correct. There were some 45Ts built with chain drives connecting the inner and outer axles, in place of the side rods.

Both models used the 733 traction motor, but with a different gear ratio. The 44T could be run at up to 35 MPH safely, track condition permitting, but the 45T was only allowed 20. I've never been on a 45T at any sort of speed, but have been told that they ride rough.

The motors can be a bit delicate; I know of one tourist operation, with just two or three coaches and a 44T, that replaced a few TMs in short order. The problems went away when the crews stopped power braking coming into one of the stations.

I have always been amazed about how well built the industrial units were, when compared with some of the earlier U-boats. Its as though the industrials were designed to last, while the larger units had to only make it to the end if their 15 year equipment trust.
