Metro-North Railroad train mechanics and cleaners say they’re gearing up for a strike, claiming the MTA isn’t sending “decision makers” to ongoing mediation talks.

But the MTA says there is “absolutely no threat” of a walkout.

Members of Transport Workers Union Locals 2001 and 2055, which represent around 600 car inspectors, cleaners and carpenters on the Metro-North Railroad, have been without a contract since August 2019.

The talks are now in federally-mandated mediation, which union leaders claim the MTA isn’t taking seriously.

“They’re sending lightweights to the mediation,” TWU international president John Samulsen told the Daily News Thursday.

“If they want to avoid a strike, they need to send a decision maker.”

The union boss said a major sticking point is an MTA demand to be able to renegotiate portions of the contract after a deal is reached.

“They’re looking to be able to reopen the contract [before it expires],” Samuelsen said. “We’re going to shut down Metro-North over that demand.”

Samuelsen said negotiations also hinged on wages, with the Local 2001 and 2055 members standing to gain less than other MTA locals, including TWU Local 100, which represents the bulk of MTA’s subway and bus workers.

In a memo sent to the other unions representing Metro-North’s roughly 6,000 other employees MTA’s labor relations director Ryan O’Connor, said there was little chance of a strike.

“We understand the unease and confusion that these types of misleading public comments cause for our labor partners, our employees, and our customers,” O’Connor wrote, according to a copy of the memo obtained by The News.

“We want to confirm and assure all relevant parties that there is absolutely no threat of an imminent legal strike from the TWU.”

Unlike MTA bus and subway workers, who cannot legally strike under New York’s Taylor Law, LIRR and Metro-North employees are governed by the federal Railway Labor Act, which permits a strike if all attempts at negotiation have failed.

The parties have an upcoming mediation meeting scheduled for August 1. Samuelsen said the union intends to seek federal authorization to strike if that meeting is not productive.

The union boss told The News he expected his members could strike by “early autumn.”

The MTA, however, has a different view of the process.

Even if mediation unravels, O’Connor’s memo reads, “the [Railway Labor Act] provides a lengthy process that includes cooling off periods with the possibility of federal intervention, all before a legal strike can occur.

“The TWU’s statements that a strike against MNR is imminent is simply untrue,” he wrote.
