MassDOT says:
Beginning the evening of Tuesday, December 12th, and continuing through Thursday, December 14th, nighttime construction work is anticipated between the hours of 11:30 PM (after the last train passes) and 6:00 AM the following morning. The approximate location of this activity will run from the College Avenue Bridge to the Harvard Street Bridge along the Lowell Commuter Rail right of way in Medford...for the leveling of newly installed track.

Starts tonight! (if all has gone to plan).

Keolis signal crews were working at two separate signal access manholes alongside the Tufts interlocking at about 6pm tonight.

Anyone have news of the overnight levelling work on the Lowell Line?

GLX team has updated its noticefor night work levelling.

Is this expected? They essentially just took the notice for Dec 11/12 and moved the dates 7 days. Does that mean:
1) they cancelled the work on the 11th/12th ?
2) The work on the 11th/12th happened but didn't get the job done?
2a) The work work on the 11th/12th was never supposed to get the job done?
2b) The work on the 11th/12th was supposed to, but fell behind?

Nighttime Construction Advisory - Medford

Beginning the evening of Monday, December 18th, and continuing through Thursday, December 21st, nighttime construction work is anticipated between the hours of 11:30 PM (after the last train passes) and 6:00 AM the following morning. The approximate location of this activity will run from the College Avenue Bridge to the Harvard Street Bridge along the Lowell Commuter Rail right of way in Medford.

The purpose of this work is to allow for the leveling of newly installed track. The primary machinery involved in this process is a leveling device which rides slowly along the rails while making fine-tuned adjustments to the track grade and alignment. Occasionally, trucks supporting the leveling process may trigger audible back-up alarms.

Tufts Interlocking progress;
- new signal hut has been dropped in the "bunp out"
- first vertical section of the signal mast installed
- additional signal mast sections are the "shiny scaffolding" I reported earlier
- two signal heads seen on site
- crane erecting it all
- ballast looks finalized on the outbound track (as seen riding on inbound track)

Additional signal hut (new to me, anyway) is alongside the switches themselves, along with what looks like the power supply and breaker boxes for the switches themselves.
