Fenway portal closed at 6pm, 09DEC14

Postby Yellowspoon » Tue Dec 09, 2014 8:44 pm

The Muddy river is about 20 inches above flood stage. In March, 2010, the river was about a foot lower. There is busing from Fenway to Kenmore. Channels 5&7 were there so it must be a slow news day. It's odd to see "FENWAY" as a destination. At Longwood, there was a train waiting for the OK to proceed to Fenway, and another one 100m behind it waiting to get into Longwood.

Kenmore station has been submerged before, that's the reason for these precautions.

Did the Riverside line tracks get inundated between Fenway and Longwood?
Did water start pooling against the sandbags at the portal?
Was there enough advance warning of the water's rising that the buses would have been dispatched and waiting at Kenmore and above Fenway Station before the portal was shut down?

How effectively could Riverside cars be run out Beacon St. to Reservoir and then continue to Riverside so people would not have to get out and stand in the pouring rain at Kenmore and outside Fenway?
(To the theater stage manager) Quit twiddling the knob and flickering the lights while the audience is entering and being seated. (To the subway motorman) Quit twiddling the knob and dinging the doors while passengers are getting off and others are waiting to board.

Technically they could do that, but the crew would have to change ends @ Reservoir as the connection tracks from the maintenance facility and the C Branch turn eastward before joining the D Branch.

They need one of those inflatable 35,000 gallon subway plugs!


That thing looks like it works great in a tunnel with no rails, third rail or catenary, signals, manways, and everything else that a mockup in a lab doesn't have...

Water never reached the tracks. "Flood Stage" is 15 feet. At that height, water is level with Boylston at Aspinwall, and with Riverway near Wheelock College. Yesterday, the water was level with the 3rd step from the bottom in the Longwood photo shown below (but it was on the other side of the levee, not on this side). In my opinion, the MBTA jumps too soon. The river needs to get to almost 19 before it breeches at the levee low point next to the Brookline Water Works (about 400m west of Longwood). Even then it will take 30 minutes to reach Fenway, which is plenty of time to put up the first of two barricades across the tracks. And if they plugged that 10-foot wide low point, the rest of the levee is at least a foot higher feet.

The MBTA had this contingency plan anticipated Monday night, a good 18 hours before it was needed.

The river was below flood stage by 1am, which was plenty of time to remove the barricades for this mornings runs. (A barricade consists of 4x6 timbers across the tracks and then sandbags in front of the timbers. The timbers are kept under lock on site and fit nicely into the slots prepared for this. The last time this was used was March, 2010.

Separately, I did take a car from Riverside via Beacon Street about 10 years ago during weekend construction. It really wasn't that difficult to change ends and then drive over to Beacon Street.

The MBTA has every right to be cautious here. The Muddy River has flooded the subway on at least three occasions, one of which was before the Fenway Portal existed. Remember that the subway passes under the Muddy River just east of Kenmore and this is the low point on the entire Green Line. Once the water starts getting in, there is no stopping it. The last instance cost millions in damage to signals, lighting, communications and other equipment. On the first occasion, the water got in through the old portal at Kenmore Sq. That is why there is a berm around it today.

The next stop is Washington. Change for Forest Hills Trains on the Winter St. Platform, and Everett Trains on the Summer St. Platform. This is an Ashmont train, change for Braintree at Columbia.

Can't be too cautious, especially when the Muddy "River" is under it's restoration project. I didn't go walking through the emerald necklace today to see where the water subsided, but I heard of decent flooding in-between Fenway and Longwood from others along the creek coming up to the berm. At ,east around 7:45 last night, there were a substantial amount of buses waiting in Kenmore to head to Fenway & several on the bridge at Fenway waiting for pax to arrive.
