Pantograph compressor

Pantograph compressor

RAIL - One additional compressor is often provided on units which have air operated pantographs, i.e. those which are raised or lowered using compressed air as the power medium. Opening up a completely dead locomotive is only possible if there is battery power and some compressed air available to get the pantograph up to the overhead power supply. After all, nothing will work on the loco without power. So, a small, battery powered compressor is provided to give sufficient compressed air to raise the pantograph. As soon as the pan is up, full power is available to operate the main compressor. (099)
