So the MBTA just posted contract J19PS01 a couple of days ago, for engineering and consulting for a $161 million Southside maintenance facility. By the layover alternatives report from 2013, of the 3 advanced alternatives only the BTD tow lot and Readville 2 are still available, given MassDOT and the T have committed Beacon Park Yard to Allston multimodal / west station. Interestingly, so far as I can tell this isn't programmed into the 20-24 CIP. Contract excerpt below.It's not viable for day storage...too far out of town and only has access to the Lowell Line. All of that absolutely needs to stay in Somerville to keep the shifts moving, though if southside can secure Widett Circle, BTD Tow Lot, or any of those pieces it will be an enormous relief for BET to be able to get out from under having to support southside day storage. Because then not only does south have its storage needs fulfilled, but Readville Yard 2 (which itself is expandable out to the banks of the Neponset by evicting the recycling center on the easement next door) gains enough flex 8 miles out to be able to play host to new full-service southside EMU and coach heavy-repair shops. Which will be enough to trim BET's shop responsibilities for the south down to just the unified diesel locomotive shop. And possibly some native MOW south storage of its own on the expansion Readville land. That north v. south relief sequence is in turn extremely critical for being able to take the Grand Junction off the RR network for the Urban Ring at all...because the Worcester-Ayer backup route for equipment swaps is only viable if you can reduce the rate of swapping from 1-2 per day over today's GJ to maybe 2 per week through Worcester County. You can hit that cost-neutralizing target of trading much-reduced moves for longer distance if the only things you're swapping each week are Downeaster sets on AMTK rotation and strings of southside diesels going for shop work or 92-day FRA inspections...and don't have any coaches making the trip and no longer have to make so many trips solely for the sake of rebalancing equipment assignments.
