A Direct Current electric motor heats up when it is drawing more current than it can dissipate. If a model locomotive is pulling too many cars, or is climbing a grade, the motor has to draw extra current to do the work. If the motor gets too hot from this excessive load, either the motor brushes or the windings melt. You can monitor what current your locomotive is drawing by installing an ameter and voltmeter to your control panel. It is worthwhile knowing what your engine's limits are. Short of that, simply monitor how warm your locomotive gets under various loads: hold the bottom of the frame against your cheek. If it's warm enough to hurt, lighten the load or give the engine a break.
