Diesel Version 5:Variable Momentum

From Train Control Systems Documentation
Jump to navigation Jump to search

TCS decoders support 3 different "Momentum Setpoints" that allow locomotives to accelerate and decelerate different across the speed range. This can simulate long trains taking a while to get going (overcoming static friction). Another use is to accelerate slowly at first to pull the slack out of cars quickly or to keep from knocking over your passengers and then once moving accelerate at a faster rate.

For deceleration a longer deceleration rate (higher value) can be used at low speeds so the slack in the train naturally will be pulled out and the cars won't bunch up from coming to a quick stop.

For instances where the decoders motor output is tied to say a windmill's blades the variable momentum CV's can be used to give a "Soft Start" or "Soft Stop"
