If Somerville ends up a two-track station, it would be ironic, given that the new bridge over Rt 206 is three-tracks wide.
Even if Somerville ends up just like Westfield and Plainfield, there woudl really be no issue with adding more tracks - the current platforms were island platofrms at one point, and could easily be again. There is room on the north side (track 1 platform) in particular that woudln't interfere with anything. The south side (track 2 platform) would be a little tricker, but still woudln't be that big of a deal, as the pedestrian underpass still is there all the way over by the parking lot.
Westfield and Plainfield are the tough ones, but luckily there are interlockings and control points on either side of the station, so while less than ideal, they could easily go from 3 tracks to 2 tracks on either end of the stations. However, there is one bridge, i believe its Crossways Place?, that is west of Westfield that was raised and rebuilt as a 2 track bridge. That could be a bit of an issue and require some work, but still doable with some cash, but it would probably be easier to move CP Scotch to the other side (west) of the bridge, and then make that into an interlocking where the 3rd track would come in...it wouldn only be a difference of about a 1/4 mile or so, not a big deal
