In my close up photos I took of those cars, other than AIR brake hoses which connected to the A/B hoses on the Motor Car Horses (Hi-V or Low-V's) -- and IRON-coupled - as the Hi-V and Low-V Motor cars at the hopper-car-coupled end had MCB Knuckle Couplers installed in place of their standard subway couplers...I don't recall any MU Sockets or cables.Remember, these early era hoppers had to run with both HI-V and LOW-V cars which had different MU control systems and differing cable sockets ! I was told by a former retired Work Train motorman pal that the head end (pulling consist) motorman used whistle signals (later radio contact) to alert the rear powered set "pushing" consist of motor cars, as to when and what "notch" to move his controller to - in synchronization with the head end motorman....as well as when to coast with power off. (And vice-versa in opposite direction). I would assume that the braking system and control of the head end first car A/B stand, would control the braking function and ratio of the hopper cars and coasting (power off) rear Motor Cars. Similar procedure as to when SETAM engines were double headed --- or when a rear diesel (or steam) HELPER unit Loco helped push a diesel (or steam) towed freight train up a steep grade. Don't know further - but perhaps the retired (or current) TA motormen here may have more detailed info. regards - Joe F |
