Considering the double-tracking of the mainline from CP-3 to CP-4 Boston Landing area after the closure, the volume of trains increased nominally, but ridership on the railroad exploded in the past 10 years or so. The double-tracking was a bottleneck for service, but the current antiquated Rule 261 signal system east of Framingham is a hindrance to adding additional peak direction trains on the line.
