    — Attempts by Waterloo signalmen to clear the points by power operation eventually exhausted point motor batteries, which are fed by trickle chargers, and a blown fuse accentuated the problem; thus, even when the points had been cleared of ice, no power was available to operate them until the batteries were sufficiently recharged.
