The days are finally numbered for a fleet of aging Long Island Rail Road train cars that have been in service, on and off, since the 1980s.

The Metropolitan Transportation Authority’s Finance Committee has approved a $2.3 billion plan to purchase 316 brand-new M9A train cars. Of those, 160 will be headed to the LIRR, marking the beginning of the end for the beleaguered M3 train cars that were temporarily brought back into service due to delays in producing their replacements.

Originally retired in 2020, the M3s were pressed back into service after issues with the rollout of the M9 trains, which were manufactured by Kawasaki.

“I think it’s about time,” said Rocco Bove, a commuter from Plainview. “You do the best with what you’ve got, but everybody’s looking for improvement.”

The new M9A cars will be produced by Alston Transportation and will include modern features such as USB charging ports — upgrades long overdue according to rider advocacy groups.

Charlton D’Souza, of Passengers United, didn’t mince words when describing the state of the older trains.

“They pay a lot of money for tickets and they get on these old clunkers that can’t go too fast. There’s no air conditioning on some of them, the toilets are smelling, you still smell the old chemicals from the urinals," he said.

According to the MTA, the first batch of M9As is expected to arrive in 2029, with service starting by 2030.

While the finance committee has given its approval, the full MTA board must still greenlight the purchase.

That vote is scheduled for Wednesday.
