Much appreciated guys.

In a model loco, this voltage willl depend on the weight of the loco and friction of its gearbox, and the weight of the train it is pulling. Most DC controllers will need to be turned up a little way before the loco will start moving.

DCC always has about 14-16 volts AC on the rails. The decoder rectifies this into DC and uses pulse width modulation (PWM) to the motor, based on your DCC throttle setting.

DCC unit require upwards of 6 volts to start moving, sound usually around 3.

Your set is DCC ready but it is an analog (DC) system. While not familiar with this set movement of the loco will be determined by how many volts the loco is receiving. If 25 is 1/4 throttle it appears high. Has the loco been broken in? Let the loco run for a while at various speeds in both directions. Do you hear the motor trying to run (humming) a while before it actually moves? If so it is binding and you will have to open the loco (remove the shell) and see where it is being restricted.
