If they double track through both Andover and Ballardvale, they would have to construct a new platform at one of the stations, as the platforms are on opposite sides of the current single track. At Ballardvale, a new platform for the current track (which would be the inbound/westbound track if double tracked) would end up on current private property. At Andover, a platform on the outbound/eastbound side should be doable, but with the town planning to move the DPW yard that is adjacent to the station on the east of the station, and redevelop the site, I'm betting that they want any station expansion/improvement to wait for and be tied in with that project.They wouldn't do all-highs on a freight mainline, and I can't imagine that's an ironclad FRA requirement. New construction projects elsewhere, like the New Haven-Springfield commuter rail line, aren't doing more than mini-highs at the all-new or expanded stations because of the freight. It would be insane because of the associated loss of revenue for not being able to run full-dimension freights, and mini-highs with ramp achieve ADA compliance so it's pointless overkill not worth the downside to mandate it.
That's even before the issue of new rules requiring full-length high platforms versus an active freight mainline get tackled. Those two stations could get very expensive very quickly when they go to the drafting table.

Was there a big ticket item between Ballardvale and Lowell Jct, like a bridge, wetlands, etc that would have significantly added to the price I wonder?Simply they ran out of money from the grant, coupled with moving a station as noted already. Additionally 1 of the 2 Shawsheen River bridges that are in dire need of repair is in this short stretch (just east of LJ). I've heard rumor too that they are going to make the interlocking at Ballardvale a crossover with a short stub track west of the new double track (toward the station). That's certainly a pretty good sign they are planning to continue the double track toward Boston in the not-to-distant future.

It's not in the cards for a number of other passenger rail projects in the country at stations deemed "new construction". So either it's a state-level ADA added requirement, or just MBTA policy independent of the law.F-line to Dudley via Park wrote:It is not an FRA requirement; it is an ADA requirement.

A requirement of the original P&S for the B&M property prevents the T from restricting freight moves they had at the time of the sale unless the railroad signs off on it.
