Full subway service has been restored on the A and C lines following a massive theft of copper cable from train tracks.

Transit crew worked through the night to repair the damage.

The crime caused delays and overcrowding for hundreds of thousands of commuters Wednesday along the entire length of the two heavily used lines. The A and C carry 775,000 riders a day and traverse Manhattan’s west side.

Officials say 500 feet of cable was stolen from about 12 locations along the tracks.

The theft was discovered late Tuesday when a train lost power north of the Howard Beach station in Queens.
