Haverhill Line

Haverhill Line is a commuter rail line operated by the Massachusetts Bay Transportation Authority as part of the MBTA Commuter Rail system. Running from North Station in Boston to Haverhill in the Merrimack Valley, the line provides critical transportation links for communities in northeastern Massachusetts. Its operations are currently managed under contract by Keolis Commuter Services.

History

The line's origins trace back to the 1830s with the chartering of the Boston and Lowell Railroad, one of the earliest railroads in New England. Service to Haverhill was later established by the Boston and Maine Railroad, which became the dominant carrier in the region for over a century. Following the decline of private passenger rail, the Massachusetts Bay Transportation Authority assumed control of commuter services in the 1970s. Significant infrastructure projects, including the relocation of the line's southern terminus into the Downtown Crossing tunnel to reach North Station, were completed in the 20th century. The Interstate 93 project in the 1970s also required major realignments of tracks near Methuen.

Route and stations

The 33.4-mile route travels northwest from the underground North Station through the cities of Malden, Melrose, and Wakefield. It shares tracks with the Lowell Line until a junction at Wyoming Hill in Melrose. The line then proceeds through the Middlesex Fells Reservation and serves stations including Greenwood and Wakefield. North of Reading, the route runs through Wilmington, Andover, and Lawrence before reaching its terminus at Haverhill. Key infrastructure features include the Salem Street bridge in Malden and the Shawsheen River viaduct.

Service and operations

Regular weekday service consists of multiple inbound trains to Boston during the morning peak and outbound trains in the evening, with limited service on weekends and holidays. The line interlines with the Lowell Line for a portion of its route, affecting scheduling and capacity. Operations are controlled by the MBTA Commuter Rail Operations Control Center, utilizing portions of the Boston and Maine Railroad's former Western Route. Major stations like Lawrence and North Station serve as significant passenger hubs, with connections to the MBTA subway and other MBTA Commuter Rail lines.

Rolling stock

The Haverhill Line is primarily operated with push-pull trainsets powered by HSP-46 diesel-electric locomotives manufactured by Siemens Mobility. Passenger coaches are predominantly double-decker Kawasaki Heavy Industries bi-level cars, which provide increased capacity. This fleet is maintained at the Boston Engine Terminal and the Haverhill Commuter Rail Maintenance Facility. The equipment is part of the standard fleet used across the MBTA Commuter Rail network, facilitating flexible assignment and servicing.

Future plans

Proposed improvements include the implementation of full positive train control and schedule adjustments under the Keolis Commuter Services contract. Long-term capital projects studied by the Massachusetts Bay Transportation Authority involve potential station upgrades at Andover and Reading. There is also ongoing discussion regarding service expansion and increased frequency as part of broader regional rail modernization efforts, which may involve coordination with the Federal Railroad Administration.
