Sounds good. The 64-dollar question is: supposing our hypothetical Erie-owning railroad of the 1950s had on staff some submarine veterans who had topped their classes at Navy electrician school during the war. Do you think they could connect a Woodward governor on a 16-567C engine to the Amplidyne excitation system? (As an alternative, could a 17 MG be adapted to control an EMD engine? I'm guessing that the final hydraulic actuators for the engine fuel rack would need changing: it seems too much to hope that FM and EMD engines had exactly the same movements in their fuel racks!)

Going back to one of your earlier responses... One of the GE design staff's aims in designing the U25B was to keep everything as simple as possible (remember the bost about only 7 (?) pieces of rotating electrical equipment above the frame). And the American railroad industry seems to be very cautious about accepting anything new and different, so there was certainly good reason for the GE people to avoid ANY feature that might scare a chief mechanical officer used to EMD power. So going with Woodward governors in preference to their in-house 17 MG is certainly understandable. ... I wonder what sort of engine governors were used on earlier GE locomotives with Cooper-Bessemer engines (70-tonners, export U-series)?
