Better Late...

I was heading into Boston today, so I decided to try to get some pictures of the new Assembly station as I passed it on the train. It helped that the train was practically empty and I was able to stand at one of the doors and take multiple photos without any obstructions:

Here's the new section of southbound track I mentioned, just north of the station.

A bit further along, just before moving into the station itself.

This will be the platform, viewed from what will eventually be the northbound side.

A stairway under construction.

The southern end of the platform.
