A report examining the planned Interborough Express — the light-rail line the MTA wants to build along 14 miles of existing freight right-of-way between Brooklyn and Queens — concludes that running the line with automated train operation would lower its long-term operating costs and let it handle more riders at higher frequency than a conventionally staffed system, according to amNewYork.
The IBX has not reached construction. It remains in environmental review and design, and no general contractor has been selected. But the automation question matters now, before a design-build team is picked, because it shapes what the eventual construction contract actually specifies: automated operation typically requires different signal systems, platform screen doors or barrier work, and communications infrastructure than a conventionally operated line — scope that gets written into the bid documents, not added after.
The MTA's active board right now carries several nine-figure design-build packages tied to its broader capital program, including the Design-Build Metro-North Hudson Line Bundle (RFI-000043, roughly $100 million, due October 21) and Design-Build Station State of Good Repair Work – Package 3 (RFI-002007, $100 million-plus, due November 3). The IBX is not yet one of them, but it sits in the same capital-program pipeline those jobs come out of, and the agency's design choices on automation now will determine what trades and specialty subs — signals, systems integration, platform hardware — get a shot at the eventual IBX construction package once it's let.
The MTA has not released a construction timeline or cost estimate tied to the automation recommendation, and the report does not commit the agency to building it that way.
Automated or driverless transit operation is still uncommon in U.S. heavy and light rail; where it exists (parts of airport people-movers, some newer international systems), it typically adds cost to the systems and signals scope up front in exchange for lower long-term staffing costs — a trade-off agencies weigh during design, not after a contractor is already mobilized.
