STAMFORD – A prospective debut date of the New Haven Line’s long-awaited M-8 rail cars remains hazy as engineers continue work to correct computer glitches that have prevented the new trains from entering public service, the state’s public transportation chief said Wednesday night.
While an earlier software problem that caused the cars to disrupt railway signal systems has been fixed, state Department of Transportation Public Transportation Bureau Chief James Redeker told the Connecticut Rail Commuter Council Wednesday various other software issues have come up that have put off a series of mileage tests for the first eight pilot cars.
“Every night we are out testing but we have not begun the official 4,000-mile test that will get us into revenue service,” Redeker said. “Once we get all systems functional and working perfectly we’ll get the 4,000 mile tests going.”
None of the cars have begun a series of simulated passenger runs in which the new cars must complete at least 4,000 miles without any significant errors, Redeker said at the council’s regular January meeting.
“An issue comes up almost every night, but we’re installing software fixes and hoping to get the mileage tests started soon,” Redeker said.
After predicting in late December the cars would be in service in late January, Metro-North Railroad and DOT officials this week declined to say when the cars would be in service.
Metro-North Railroad President Howard Permut and DOT Commissioner Jeffrey Parker last month acknowledged software glitches would prevent a long-discussed debut by late 2010.
Rail Council Chairman Jim Cameron asked Redeker to inform the council and the public about any significant new software problems that could hold up the trains until spring or later.
“Please keep the council updated and let us know what’s going on,” Cameron said. “We’ll expect to see the cars in the future.”
