Nice job, Bill! Jim, those trains we ran used straight DC for power. The placement of the helper locomotives 2/3rds of the way back in the train was according to Santa Fe practice for helper units at the time. The objective was to have the helpers shove some of the cars ahead of them while pulling the remainder of the train, thus keeping coupler stress to a minimum, and preventing "stringlining", etc., on curves.
On Santa Fe at the time, remote consists could be controlled separately or in "MU" mode. The latter is what we used on the trains we ran on DC. Further, the remote consist was always slightly less powerful than the lead consist, to prevent the possibility of "buckling" a train. Undulating territory, unless exceptionally severe, was not an issue, since the slack on the cars ahead of the pushers ran in and out as the grade, or loading, changed, as you and I observed by adding and removing weight the the open cars in the train.
