KB608: Locomotive Throttle Response

Why do my trains start moving at 25% throttle?

You may need to adjust some CV values

Check the value of CV02, start voltage; the default setting is 0 (zero).  You may need to adjust this value.

Check the value of CV03, acceleration rate; the default setting is also 0.  It is possible that the locomotive has been set for a slow acceleration rate.

You can also adjust how each locomotive responds to throttle inputs by programming loadable speed tables or 3 step speed tables.

If you decide to reset the decoder to factory default values , set CV08 to a value of 08 to reset the decoder back to its default values and start over.  If you wish to preserve loadable speed tables when you reset, program CV08 to 09.
