Saugus Draw Failure

Postby StefanW » Fri Nov 04, 2011 6:47 pm

The conductor & engineer on #18x just told me the track #2 across the Saugus Draw (Eastern Route mainline) has been suddenly taken out of service - and it will be out of service for something like 6 months! Apparently the Army Corp of Engineers surveyed the bridge today and found the pilings deteriorated enough to mandate an immediate closure of track 2 (inbound).

So from now on every train is going to be competing for track 1 between Wonderland and Brickyard! It's going to be hell!

Might the dispatchers tell us which trains would be affected by track 1 occupancy, assuming the timetable operative?

Preference will be given to inbounds in the AM and outbounds in the PM. But if some trains are delayed from late turns then more than likely it will be first come first serve through the 4 miles of single track this has created.

Is there a plan for emergency fixes ASAP, or is this 6-month restriction a stopgap to buy time that could end up stretching much longer than a half-year?

This all took place late on a Friday afternoon. The plan to fix this was being worked out on a limited basis yesterday. Expect a real plan to formed early this coming week.

They will use the southbound platforms at Lynn and GE for all stops? Seems that way.

Not sure exactly what you mean by Southbound. Direction of travel to Boston is West and the direction towards Newburyport is East. The only station that is effected by the single track is River Works. Since that is a railroad crossing and not a platform it does not really effect the side people normally wait on. Both tracks are in use at Lynn Station and I would expect normal operation there.

I wonder if it would be easier to install a switch at each end of the bridge to reduce the single track to a smaller block. If the whole draw is deficent and needs to be replaced it would be beautiful if they provisioned for four tracks for a future blue line extension.

...I didnt sleep much last night so I guess I'm probably dreaming.

If this is going to be a long term issue, one cross over on the Boston side would be logical. I have actually said this at work, so you aren't dreaming about an idea that would work!

What about putting in just a spring switch, #20 frog, from track 2 with the points just west of the trestle for track 1. It might not be necessary to move the eastbound home signal (9.61?) yet still have clearance from fouling. Should be cheaper and guarantees no entry to track 2 from the west.

The T now has put out an advisory about the delay on the Ts web site.

This time the advisory is different from the one last Friday. At that point it was just rush hour delays, now they have rightly determined that any/all trains may be affected...

A friend of mine in the business found and shared with me this great collection of photos and plans for this bridge!

http://www.loc.gov/pictures/item/MA1362/

Notice the "Significance". (I added the bold & underline emphasis)

Library of Congress wrote:Title: Saugus River Drawbridge, Spanning Saugus River at MBTA Railroad Eastern Route, Saugus, Essex, MA

Other Title: B&M Eastern Route Bridge 9.55

Creator(s): Historic American Engineering Record, creator

Medium: Photo(s): 45 (4 x 5 in. and 8 x 10 in.)

Data Page(s): 7 plus cover page

Photo Caption Page(s): 4

Reproduction Number: [See Call Number]

Call Number: HAER MASS,5-SAUG,2-

Repository: Library of Congress, Prints and Photographs Division, Washington, D.C. 20540 USA

Notes:
Survey number HAER MA-84
Part of building/structure is in Lynn, Essex County, MA.

Significance: The Saugus River Drawbridge is a single-leaf Strauss overhead counterweight bascule which is believed to be the oldest known example of its type in Massachusetts. It is particularly significant for its innovative engineering design and association with a prominent bridge engineer, Joseph Baermann Strauss, whose company designed the Golden Gate Bridge in San Francisco.



I never appreciated how cool the mechanism is! Going from closed to open, the counterweight moves mostly in the vertical direction:
