Sir, – Further to recent correspondence (October 13th, 14th and 15th), perhaps a reason for the reduction in the number of fights on the roofs of trains in films lies in the fact that a very high percentage of trains nowadays use a pantograph and overhead high-voltage line system, so that a contest on a train roof could turn out to be an electrifying experience. – Yours, etc,
DAVID KELLY,
Killiney, Co Dublin.
