Thank you both for your kind inputs.
Yes, i can imagine how strong should be the connection to the locomotive, the impressive strong shears they need to support, of course regarding the moment to start to move the train because the couplers are mounted in front of the span bolster. I've realized from some pictures the points where the shears should be applied, the coupler first, then the pivot point of the first B+B truck (outter) and then the span bolster connection point to the locomotive.
Since this locomotive was used in cargo trains (heavy), i think they were condemned to fail due to the uge maintenance costs of the trucks (i can imagine the failure of the pin points???) I can't find also if the first and second generations of the GTEL used the same solution, B+B trucks with the span bolsters.
Regards
Be safe
