Working for the manufacturer (Pratt & Whitney Canada) of the turbine engine for the JetTrain (truly a misleading name, but I'm not in Marketing) I can give you some facts:
The turbine is a ST40 that produces about 5000 HP, weighs about 3000 lbs (about 38000 lbs less than a comparable diesel engine). The cyclic power demands are definately a concern for the turbine, but improvements in cooling within the engine remove any worrys. As for the mention of the the train with 10 1960's era PT6's: 10 engines @ ~350HP = 3500HP weight: 10x400lbs = 4000lbs BTW Bombardier has to add about 6000 lbs of dead weight to the locomotive to ensure proper traction...
