I see no evidence that either CSX or MASSDoT seek to reduce freight activity east of Worcester on the Framingham line - in fact, their effort is just the opposite: interchange traffic is building on G&U at N Grafton, and at Middleboro for Mass Coastal, C&D traffic is building on CSX operated lines radiating out of Framingham to Leominster and SE Mass. Net: Nevins Yard, N Framingham yard, the Ag Branch, and Framingham Secondary track at Framingham will continue to be strategically important for CSX and MASSDoT.
One other point: if somehow the Concord St (rte 126) grade crossing were eliminated at the Framingham depot, the 20 daily eastbound T trains could be sped up greatly as they would no longer need to proceed at restricted speed from CP-22 approaching the currently always red indication at CP-21, which is done so the crossing gates don't come down until the eb commuter train is ready to depart the station platform.
