Although terribly hard on themotors this would not injure the controller were it not thatthe motorman frequently throws the reverse handle back to forward position before the motors have come to a result is a very severe arc between the contacts on thereversing drum, which is likely to injure the controller. In this new controller all contacts which carry the full cur-rent to the four motors in multiple are made double width, andhave two of the standard contact fingers instead of one.
