Good luck with it. I have had 2 of these & found that running on 072 is not feasible. Cars kept coming apart on curves .
The steel frame part that joins the cars must have been bent slightly out of shape.
I have Atlas O 72" curved track and have run the TurboTrain well after bending the connection points that are part of the steel frame carefully into the right position.
The cars then stayed together.
The TurboTrain that I have runs smoothly. It is slower than the GP9s that I have.
