I don't think they are "bad on the track" generally speaking. "pressure on the rails" does not compute. If I understand correctly the big issue FGLK had with them was there were too many places they could not go due to the long wheelbase. Inside the army base? Guaranteed derailment. Around the curve at Victor Insulators? Forget it! Phelps Supply? Not a good idea! 4 axle power is more versatile and flexible in the assignments it can work.
