210.  Q. If the locomotive brake creeps on with the automatic and independent brake valves in running position, where would you look for the trouble?

A. This is caused by the pressure chamber being overcharged or a non-sensitive feed valve allowing brake pipe pressure to vary, which in turn causes an automatic application of the brake.

211.  Q. How often should the main reservoir be drained?

A. The main reservoir should be drained at the beginning of each trip.
