Indeed. My N class with 2 motorised bogies & the engine motor inside runs no
better (grade-wise) than with 1 motorised bogie, and actually causes a single
controller to cut out (I assume a heat switch) after an hour or 2 constant
running.
Also I've found putting a weight brick in the fuel tank (low CoG) increases
cornering stability as well as traction.
