 Hello everybody, I kindly ask if somebody can provide me with tractive effort tables (shaft force, wheel-force, any data is welcome) for F-3 / F-7 (GP-7) and GP-9 units at speeds 0-70 mp/h in 10 mp/h iterations? I would like to compare them with a couple of steamlocomotives. - What were the usuable min. cont. speeds of them? Could these early units run safely at full  power around 10mp/h? - If the Units were coupled together, could the forces be simply added the way: 1x F-3 cont. TE @ 10mph = 40,000 lbs 2x F3 @ 10mph = 80,000 lbs ? Have many thanks in advance and a nice weekend! lars
