In the General Settings menu you can set other parameters that affect the operation of the program.
Default speedstep: when adding a new locomotive, this speed step will be set by default.
Default speed unit: when adding a new locomotive, this speed unit will be set by default.
Stop loco at direction change: if this is enabled, if you change direction with the locomotive while moving, the program will first issue a stop command and then change direction. Thus, after a reversal, the locomotive does not start in the other direction.
