limited electrical pickup or dead frogs to ensure reliable operation of any locomotive in your fleet

and pulling a train:

Our PBM has onboard microcontroller and other electronics that will output a fixed voltage similar to a good power supply output so lights stay constant while PBM is active and locomotives perform better

allows for the calculation and display of the train's scale speed
