Power surge temporarily disrupts subway service

NEW YORK Con Edison says the voltage surge was caused by two breakers opening at around 4:43 a.m., de-energizing a 345,000 volt feder.

Customers experienced light flickering, but no outages were reported.

However, the surge caused signal problems in the Westchester Yard in the Bronx, delaying the departure of some subway trains for their morning runs.

The problems were fixed for the bulk of the commute, but straphangers were told to expect delays on No. 4, 5 and 6 trains. Service, however, is back to normal.
