Under a tight deadline to open the Second Ave. subway by December, crews had to fix a screw up — the tunnel was too narrow for some trains, the Daily News has learned.
Crews had to shave down parts of a tunnel wall because train cars 75-feet long were unable to fully clear curves, sources said.
Those 75-foot-long train cars are used on some lettered lines and need to be able to go through the tunnel for those times when transit workers have to move equipment around. The Q trains that will be running through the Second Ave. line use a sleeker 60-foot model of car.
“I would assume you would build the tunnel to accommodate the various types of (letter trains),” Andrew Albert, a Metropolitan Transportation Authority board member, said. “You may be called upon to move equipment around so it’s just a safe thing to have all of the operational equipment use that tunnel.”

The MTA ran a train known as a track geometry car to spot the locations where adjustments to the tunnel had to be made, according to the agency.
The adjustments to the wall’s diameter were made last week, according to spokeswoman Beth DeFalco.
“There is no change to the anticipated date Second Avenue will be open,” she said. “Tests are conducted as part of the overall process to get the tunnel ready and are done precisely so that we know what adjustments may be needed. Training runs are now being made regularly with 75-foot cars.”
MTA officials last week said that trains had made their first test runs over the tracks of the Second Ave. subway. A video taken from a Lexington Ave.-63rd St. station platform — the first stop for the Q line on the Second Ave. subway — showed the longer train cars moving through the tracks.
Second Ave. subway needs to ramp up testing to open in December
Officials have been racing to get the new line open in December, but independent engineers overseeing the project have warned MTA brass that it needed to ramp up its testing of key equipment, such as fire alarms, radio communications and elevators.Send a Letter to the Editor
