Shunting Mode

The purpose of a shunting or switching speed mode is to create a more realistic performance during switching operations. This mode is available in some multifunction decoders. By setting this CV, the top speed of the locomotive is usually reduced to half, and the acceleration and deceleration variables are changed as well.

This feature is more useful with a Road Switcher, as it is a multipurpose locomotive, usually employed on local freight trains. A speed table can be created for normal operations, and shunting mode engaged when switching operations are performed.

Activation

By pressing a function button on the throttle, this mode can be activated when needed. The mode must be enabled in the decoder for this feature to work. When deactivated the decoder returns to the normal speed table and momentum settings.

Decoder Support of Shunting Mode

A number of multifunction decoders support Switching Speed Mode. Read the instructions to determine how to enable this mode, as the CV used will depend on the product.

Digitrax

Digitrax calls their mode Switching Speed, which is available on their FX3 decoders.

ESU

ESU uses the term Shunting Mode. It is available on their LokSound multifunction decoders.
