Bob, Yes, the B unit generated the electricity which powered the traction motors on the A unit. Also, the water cooling the turbine in the B unit was controlled by running it through radiators in the A unit. There were many hoses and electrical cables between the A and B units of the gas turbine locomotives. From the frame to the roof there air brake trainline and MU hoses, electrical control MU jumper cables, electrical power cables, and cooling water hoses. If you ever wondered what those four little tabs (two on the A unit and two on the B unit) were at the end of the roof between the A and B units, they are supports for the cooling water hoses.
BTW, the diesel engine in the 4500 HP turbines were Cummins engines, and the diesel engine in the 8500 HP turbines were Cooper Bessemer.
