DEFINITION

Classification: 246/64

(under subclass 62) Systems in which the source of current is a battery or dynamo placed upon the train.

(1) Note. Systems in which train-batteries actuate local train-circuits or supply current used for purposes other than signal actuation or control are not here included, but will be found in the appropriate line-battery classes.
