Hello Rich,

Your last paragraph also answers your question - variable inertia.
What most operators require from a model is the ability to instantly stop at the point of touching up to the wagon(s)/cars i.e. no loco inertia for precise 'spotting'. But some model 'drivers'/engineers like the idea of a train/loco gently coasting to a halt after cutting the juice.

This is totally unlike the prototype where it is very difficult JUST touching up to a wagon (a wagon whose end & buffers/knuckle you cannot even see from the footplate and a real loco that itself cannot stop instantly, no matter how slowly moving. It's terribly easy to send the wagon rolling off, especially with spring/shock absorber buffers.

This is where DCC offers the best of both with multi step motor control. For ultimate model realistic experience, leave the inertia 'On' & learn to judge your model loco's exact deceleration rate to a fixed point. Then repeat that all day long in rain, wind, heat & frost etc. etc.
