How deep is this tunnel in Fairfax County?
WHAT tunnel? :blink:

Some folks need to read with less speed and cite when they write. :giggle:
The Silver Line in Tysons has a ~1500' long tunnel between the Tysons Corner and Greensboro stations that goes through the ridge line northwest of the Rt. 123 and Rt. 7 intersection. The tunnel ends at the Greensboro station. Since the tunnel cuts through the ridge at the highest point in Fairfax County (marked by the communications tower placed there), to answer Andrew's question, it is not a deep tunnel.

BTW, the Dulles Metro October 2013 newsletter has photos of the elevated track & Spring Hill station from above and one from ground level of the Tysons Corner station for those interested.
 
The 50.5 miles of tunnel has to be for the entire system spread over Maryland, DC, and Virginia.

Some of that should have been on the surface or aerial. Underground is far more expensive both to build and to operate than any other form of construction.
 
The November 2013 newsletter (2 page PDF) for the Silver Line project has been posted. Has photos of the elevated tracks, new stations, and installed fare machines as well. Getting close to completion. Geotechnical test bores are continuing for Phase 2.

There is still no date for start of revenue service for Phase 1 beyond some general pronouncements about possibly starting in February 2014. Which I interpret as meaning no earlier than the last Saturday in February.

PS. The underground DC Metro stations will all be getting new lighting over the next 2 years. PlanItMetro website info on the upgrades: New Station Mezzanine Lights Show the Way. The stations do need better lighting, just hope they are not overdoing it.

Yep, you be right...

From this article at WTOP:

The Metropolitan Washington Airports Authority is again pushing back its expected completion date for construction of the new Silver Line through Tysons Corner.

The airports authority, which oversees construction of the new commuter line, says it needs several more weeks to complete work. Its most recent estimate had been that it would finish up at the end of November.

Because the Washington Metropolitan Area Transit Authority, which operates Metrorail, estimates it will need 90 days to conduct its own tests, passengers are unlikely to ride the line until the end of March.
 
Yep, it appears that it is now likely a March, maybe April, start date for Silver Line Phase 1. Whether WMATA needs a full 90 days for testing, filling the allotment of new hires, training, coordination with bus route changes, emergency services training & exercises, after the extra delays is not that clear. The delays should be giving WMATA extra time to prepare, hire people, train them, and so on. But they probably won't announce a specific target start date until a month or 6 weeks before.

My guess is that WMATA management is ok with the delays because it means that they won't have to provide rolling stock and cut into their reserve capacity for Silver Line operation for as many months until the Series 7000 cars start to enter revenue service. The first set of Series 7000 cars are supposed to be delivered for testing in December with an initial operational date of later 2014. I have seen a number of news reports recently of rush hour delays due to problems with the cars. They may be hard pressed to sustain Silver Line service if Series 1000 and 4000 cars break down too much.
 
After a period of dead silence, there was an update this week on the status of Phase 1 of the Silver Line. Washington Post: Silver Line close to completion but still no opening date. They believe they have solved the software problems and are planning to hold formal simulated service tests on the evening of January 25. For the tests, they will run 10 eight car trains between the Wiehle Ave - Reston East and the East Falls Church stations. If the system passes the tests and the check list get checked off, then MWAA could turn the the tracks over to WMATA in early-mid February. Which leads to a likely May start of service date.

Meanwhile, WMATA has posted a Silver Line Introduction video, 4:51 long, on Youtube. Video of the stations, tracks, etc for those interested.
 
Meanwhile, an audit by DOT's IG of MWAA's handling of the almost $975,000,000.00 in federal funding it has been granted for 'Phase One' raises questions about the Authority's ability to manage all that dough...

From this article in The Washington Post:

In one example, MWAA used $16,000 in grant money to pay for lobbying services – even though such an expense is not allowed under federal rules. The lobbying services were provided by former MWAA board members.

In another instance highlighted in the report, the airports authority used grant money to pay for $54,000 in expenses related to the second phase of the rail project, even though the dollars were specifically earmarked for Phase 1.

Auditors found that MWAA does not have a reliable system for tracking costs and determining which expenses were eligible for federal dollars. Authority officials also could not provide supporting documentation for millions in expenses, auditors found. And while some of the money may have been spent properly, MWAA officials lacked the records to prove that was the case the report said.

With an estimated $289 million in federal funding still unspent, auditors said it was critical for safeguards to be put into place to protect taxpayers’ investment in the project.

The Federal Transit Administration, which is overseeing MWAA’s management of the project agreed.

“FTA continues to work diligently with MWAA to ensure that internal controls are developed and implemented and we share the OIG’s concerns that MWAA must develop corrective actions for the deficiencies found in this and prior audits,” wrote FTA Adminstrator Peter Rogoff in his response to the IG’s findings. “We recognize that while some progress toward greater accountability has been made, more work remains to be done in the area of internal controls.”

MWAA officials said the agency was working to improve its record-keeping and address the other recommendations.
Here is a link to the IG's report.

Phase 1 of the Silver Line may finally be completed and ready to be turned over to WMATA. WTOP story: Metro Silver Line closer to an opening date this spring. If MWAA and WMATA accept the contractor's work during the 15 day review, revenue service for Phase 1 could start on a Saturday in May.

WASHINGTON -- After months of delays, the Silver Line is finally taking a big leap closer to opening in Northern Virginia.

The contractors building Phase One of the Dulles Rail Project say they have reached "substantial completion" Friday of the new stretch from East Falls Church to Wiehle-Reston East.

The Metropolitan Washington Airports Authority says they will immediately begin their 15 day review of the project to confirm that has reached "substantial completion."

Once they do that, they can turn the project over to Metro for the first time.
There was also information posted on-line that the contractor for Phase 2 will start next week to drill and build 3 pairs of test shafts at Dulles Airport to verify the load bearing capacity of the foundations for the elevated segment of the railway through Dulles. So construction for Phase 2 is getting started.
 
Depends on how you define construction, I guess. I recall reading somewhere that drilling work has already started at IAD.
That could be the drilling for the test shafts or the preperation for it. The notice that was posted on rr.net referred to the test shaft that will be drilled in the median of the access road to Dulles with the barriers going up the week of February 10. It says that "The two other test shaft pairs are being constructed in locations at the airport that are not visible to the general public." So maybe they are already started drilling those. The test shafts, BTW, will be 6' in diameter and ~39' long with ~ 50 yds of concrete and lots of rebar. So these are not small test borings.
 
While the date for the start of revenue service for Phase 1 of the Silver Line is now vaguely set for mid to late summer (maybe), there is some good news for the financing of Phase 2. The US DOT has signed off on a $1.9 billion low interest rate TIFIA loan for Phase 2, the largest TIFIA loan ever. The low interest rates will help keep the tolls lower on the Dulles Toll Road as the DTR tolls are being used to pay off the debt for the 23 mile Silver Line extension.

Washington Post: Silver Line to get nearly $2 billion federal loan. Excerpt:

The Silver Line project will receive nearly $2 billion in a low-interest, long-term federal loan to help pay for the second phase of the project that will extend the new line to Dulles International Airport and into Loudoun County.

Transportation Secretary Anthony Foxx has signed the Transportation Infrastructure Finance and Innovation Act (TIFIA) loan, the largest in the history of the federal program, Virginia’s congressional delegation announced Thursday.
 
From this report at WTOP:

In an update with reporters Monday [5/12/14], project officials described the latest hiccup that could delay the project yet again: Signals are misfiring, telling approaching trains to stop because a train is on the track ahead, even when no train is there.

Testing was needed to determine how long the repairs would take, and it's unclear whether it will affect the planned opening.

But Rob Troup, Metro's deputy manager for operations, said he was encouraged that progress is being made to resolve a list of other issues that must be addressed before Metro would take over the line.
And at least the error is a false postive, unlike the situation at Fort Totten a few years back.
 
Sand Box John has posted new photos of the construction work for Phase II of the Silver Line from a March 28, 2015 site visit. Work is now underway at 3 of the 6 station sites. The piers for the elevated track through the land at Dulles Airport have been going in since late last summer, IIRC. I expect the construction work will begin to really get underway this summer. Thought some might be interested in looking through the photos.
 
How long would it take from DC downtown to Dulles Airport?
It will take about 50 minutes for the Silver Line trip from the Dulles Airport station to Metro Center.

The scheduled trip time for Wiehle-Reston East to Metro Center is 41 minutes (and 18.8 miles). The Dulles station will be about 6.5 miles from the Wiehle-Reston East station with 3 stops in-between: Reston Town Center, Herndon, Innovation Center. So, figure about 10 minutes from Wiehle-Reston East to the Dulles stop when Phase 2 opens.

The Loudoun County board, BTW, has chosen Ashburn (now Rt. 772) and Loudoun Gateway (Rt. 606) as the names for the stops west of Dulles. The WMATA board still has to agree to the proposed names, so there is a chance they will reject Loudoun Gateway as too vague. But I doubt the WMATA board will do that. So when Phase 2 opens, one could take a trip from Innovation Center to Loudoun Gateway. Bleh. :rolleyes:
 
It has been announced that the earliest Phase II will be in revenue service is now 2019. This is being blamed on new storm water management regulations a both the federal and state levels, which is said to have caused WMAA (the airport authority) to go back to the drawing board, though I believe some of the operational problems encountered in getting Phase I into revenue service are also to blame. But don't worry, the new sprawl spurred on by Metro coming to Low Down, err, Loudon County will more than offset any improvement in the water quality of the Chesapeake Bay watershed, while the WMAA has found something to blame other than their ineptitude.
 
To revive this thread, the Phase 2 construction of the Silver Line is well underway. The heavy construction and digging started on the grounds of Dulles Airport and really got underway outside of the airport late last summer. The April 2016 project newsletter (2 page PDF) has several photos and update on the construction status.

Direct link to the photo of the hole in the ground where the Dulles Airport station will go.

With single-tracking in effect beteen East Falls Church and Ballston on the Orange Line when I rode two weeks ago, the time from Dulles Airport to downtown D,C. Was about 75 minutes.
