A PROPOSAL to build a railway tunnel under Boston, Massachusetts, connecting its two currently isolated commuter rail systems is being considered by planners, with a public consultation underway.
The idea, known as the North South Rail Link (NSRL), is not new – previous plans developed in the 1990s form the basis of the current plan.
Underground stations would replace terminus stations at Boston South and Boston North, and although Amtrak services also use both termini, they are likely to continue to serve Boston South, with the few Amtrak services using Boston North, re-routed to alternative stations.
Around 6km of new tunnels would be electrified, meaning the entirely diesel loco fleet used for Massachusetts Bay Transportation Authority (MBTA) commuter rail services would need to be replaced by bi-mode or electric locos, should large-scale electrification of the rest of the network take place.
