Presumably another benefit is the cost savings from not opening the station (no station manager, etc. needed). That's vs. the hassle of off-loading onto a bus.

The bus bridge for the Eastern market was well organized and it seemed like metro had a bus running every 2 minutes, which is in some ways an improvement over normal weekend metro service except for very long trips. I can't imagine that hiring all of those drivers was very cheap. I wonder what the additional cost is to metro for using bus bridges versus single tracking or if the relative speed of the maintenance work makes up the difference.

Bad tasting medicine, but probably better than dragging it out. Hopefully the escalators in Dupont and Van Ness will be working on January 29th of next year.

Does this mean that trains won't be running on ATC until Fall of 2012?

by Neil Flanagan on Jul 14, 2011 2:12 pm  

I'm all for the shuttles, but in some areas it makes sense to run shuttles from additional stations. For example, how many people are riding back and forth between Vienna and West Falls Church? Probably not too many. Those passengers are probably continuing on down the orange line. In situations like this, shuttles should run between Vienna, Dunn Loring, and West Falls Church and East Falls Church instead of getting people back onto a train to ride for one or two additional stops.

Closing stations allows trains to turn around immediately, as opposed to either waiting for a single track to open up or slowing down the headways so much that you don't have to wait. The sections of the line that are still open have two fully operational tracks throughout the course of the work.

And I've found shuttles to be more frequent, if slower moving, than trains going through single-track sections.

The reason why there are so many weekends related to the Dulles extension junction (K and N Junction) is. Beside installing 2 #14 junction turnouts west of Great Falls Street they will also install a totally new double crossover east of Great Falls Street. The grade profile of the existing K route orange line track will be modified as part of the installation of the new interlocking. In addition to the installation of these 6 turnouts they will also have to install conduits in the ground at the new track work for the third rail. Also as part of the K and N Junction project the contractor doing the train control contract for Dulles Transit Partners will install all new track circuit hardware to control the movement of train through the new interlocking that will be controlled by a totally new train control room to housed in the existing Fisher Avenue traction power substation.

I applaud this decision. At least Metro is showing a willingness to move faster than they have in the past. My experience with the shuttles over Memorial Day weekend was great. Hopefully now that they have ironed out the process with the shuttles, all these closures will go smoothly.

by MJ on Jul 14, 2011 2:34 pm  

When the closures are in effect and you re-enter after taking the bus bridge, are you charged as a separate trip or is WMATA smart enough to count the entire trip as 1?

by AM on Jul 14, 2011 3:06 pm  

@AM:
Let's take a hypothetical trip:

You're traveling from Metro Center to Vienna. The closure is between East Falls Church and West Falls Church.

When your train arrives at East Falls Church, it goes out of service. You exit and go down to the mezzanine. All of the faregates are standing open.

If you are going to the shuttle bus, you walk through WITHOUT TAPPING YOUR SMARTRIP or inserting your farecard.

If East Falls Church is your final destination, *DO* TAP YOUR SMARTRIP or insert your farecard. Otherwise, the next time you try to enter the system, it will not work correctly.

When you get off of the shuttle bus at West Falls Church to continue your rail trip, the faregates will be standing open. DO NOT tap your card. Go down to the platform and board your Vienna-bound train.

If West Falls Church is where you're entering the system for the first time, and you're headed toward Downtown, do not go through the mezzanine, just get on the shuttle bus. When you get to East Falls Church, the faregates will be standing open. DO tap your card as you go through, otherwise your card won't work when you get to the station you're actually exiting from.

At the suburban stations as well I can make the decision to park (if available) at the next station in and while I have to drive a little farther I make up for that in time. All it takes is for me to be aware of which stations are being closed.

by Canaan on Jul 14, 2011 3:28 pm  

I don't know why we're still appending things to Metro if we can't keep the lines we've already got open full time.

Weekend closures are common on other two-track systems around the world during periods of intense rehabilitation and rebuilding.

by andrew on Jul 14, 2011 3:51 pm  

Hm.

That's (a lot) more closures than I thought there would be. In the past, when Metro chose to those total closures, they did MASSIVE amounts of work. I don't necessarily see that here.

Here, I see them closing the same segments several weekends in a row, and silly things like running shuttle trains between Rockville and Shady Grove, and then closing that segment the next weekend.

Also, why are Metro not using concrete rail ties to avoid this mess 15-20 years from now when the wooden ties have all rotted again.

Oh, and what are these Guarded #8 switches, and why are they so important?

Still. Nice to know about this stuff a year in advance.

by andrew on Jul 14, 2011 3:56 pm  

One thing that isn't clear is that if your final destination is West Falls Church (in Matt Johnson's example) you tap/swipe at EFC and then when you get off the shuttle you just go on your merry way.

One small problem during the Memorial Day closure is that Metro employees were telling people to not swipe on the way out of Federal Center SW when in fact if you were going to any of the closed stations, you had to swipe. If you were taking the shuttle to the end and reboarding the rail system, only then do you not swipe.

by MDE on Jul 14, 2011 4:21 pm  

Also, can we start calling this "Work on the Line?"

by Neil Flanagan on Jul 14, 2011 4:42 pm  

@andrew

Oh, and what are these Guarded #8 switches, and why are they so important?

Guarded #8 switches refer to guard rails at switches. (The #8 just represents the angle of the switch) Metro had quite a few low speed derailments while trains were passing over switches a while back (I think one series of car in particular was causing most of the problems), mainly in the yards as I remember. I want to say that this is one of those NTSB recommendations that Metro put in guard rails at every similar switch.

by Mainland on Jul 14, 2011 10:53 pm  

Whoops....yep, Metro actually calls it an NTSB recommendation, d'oh. Well, here's some background on the yard derailments:

@ adam l:In situations like this, shuttles should run between Vienna, Dunn Loring, and West Falls Church and East Falls Church instead of getting people back onto a train to ride for one or two additional stops.

I am not sure that is possible, but metro should offer the option of separate bypass buses and destination buses. Bypass buses would bypass the entire interruption, while destination buses would go by every station in the interruption.

For this weekend's EFC-WFC there would be no difference, but when there are stations that are closed, it would save bypassers a lot of time.

by Jasper on Jul 15, 2011 12:21 pm  

When the stations are closed does Metrobus or other local bus service in the immediate area go up by any amount or is it the same ?

by kk on Jul 15, 2011 1:53 pm  

I've got to admit, when they closed Eastern Market, it worked pretty well with the shuttles.

by betatbox on Jul 15, 2011 3:26 pm  

Had the unfortunate experience over the weekend of METRO's unannounced (to my knowledge anyway) track work on the Yellow/Blue lines from Braddock Road to Huntington. They were single tracking...causing 20 minute or more delays with no warning unless you happened to read the message Board on the platform when it was working. METRO staff were their usual non-helpful selves...not answering questions by 'pointing' to the platform to stand on for trains. This is hardly 'world class'.
