STAMFORD, Conn. (AP) _ State transportation officials say they are working to eliminate glitches in new commuter trains traveling between Connecticut and Grand Central Terminal in New York.

The Connecticut Post reports that the pantograph arm, which connects trains to overhead electric wires, flexes too much. A state transportation agency official tells the Connecticut Commuter Rail Council that because of the design problem, the average mileage traveled by new M-8 cars without performance problems fell below 100,000 miles in September.

Metro-North Railroad’s M8 traveled an average 85,219 miles in September before necessary repairs, down from 126,103 miles in August.

Metro-North says the design glitch and other M-8 equipment problems are being addressed with the manufacturer, Kawasaki Rail Car Corp.

Kawasaki and Metro-North also will retrofit cars to stop a banging noise originating from couplings linking cars.
