WILLIAMSBURG - Straphangers who ride the "L" train say delays have become more prevalent the past few months.

Transit workers say the delays are because the train is run on a computer system, Communications-Based Train Control, which has glitches.

The MTA admits there's a problem that sometimes causes emergency brakes to be applied and can cause delays of up to an hour.

Assuming the glitches get worked out, the MTA plans on rolling out the computer-based system on other lines. The total cost will be $450 million, the MTA says.
