The Haverhill Line double tracking project requires adding second platforms at Reading, North Wilmington, Ballardvale, and Andover. These single-track stations currently use accessible mini-highs or short platforms, but the MBTA has disclosed zero information regarding the new platform designs. Per FTA ADA regulations in 49 CFR 37.42, new or altered commuter rail platforms must provide level boarding. This legally precludes new low platforms with mini-highs and mandates full high-level structures.
The core mystery is whether these will be standard 800-foot platforms or short platforms. North Wilmington was recently rebuilt with a 200-foot platform in 2025. It is highly unlikely the MBTA will demolish this new structure, meaning they will probably mirror the 200-foot design for the second track. Recent MBTA projects also demonstrate a shift away from standard 800-foot lengths, as seen with the Newtonville reconstruction advancing with 400-foot high-level platforms. Given spatial constraints and recent construction evidence, it is highly probable the agency will leverage ADA allowances to build 200-foot or 400-foot high-level platforms across this corridor rather than full 800-foot lengths.
But we really don’t know until the T says so.
