Nostalgia & History > EMD FTA & FTB General Arrangement Diagram Plate 3766

The FTA & FTB General Arrangement Diagram Plate 3766 posted is from my copy of EMD Locomotive Instruction Manual 254. Plate 3766 is a foldout that I had to divide in order to copy. This diagram is of the standard FTA &FTB arrangement offered by EMD.  The A and B were each 48'3" in length with the overall combined length of the two units being 96'6".
Hope you find this interesting.

Thanks, that clears up the issue of the original battery locations.

Amazing when you compare a current unit that all the parasitics were mechanically driven, ah progress!!

Not only that, but the cooling fans had to be "clutched on" and "clutched off" on EACH unit in the consist, based on the cooling needs of each prime mover. Kept the "Fireman" pretty busy back in those days.

True also for E units through the E7, no? I was always surprised that the cooling fans on the very early EMC's weren't turned on and off by thermostats. Seems simple enough.

No. Even the E3, E6, and E7 units all had electric cooling fans with ETS, i.e. Engine Temperature Switch control.
