WMATA's Corrective Action Plans: Safety Targets Unmet
Numerous Metro system "corrective action plans" (CAPs) -- safety fixes recommended after audits, accidents and other incidents -- have languished for years in a system operated by Metro managers and independent monitors from the Tri-State Oversight Committee, including several stemming from a dangerous collision between trains at Woodley Park station in 2004. A sampling of some of the agency's unfinished work as of Dec. 19, 2009, is below, sorted by their Metro-assigned priority levels (Open-1 is most important).
|Source||Date Filed||Findings||Identified Action||WMATA Comments||Tri-State Oversight Committee Comments||CAP Approved by TOC?||Proposed Completion Date||CAP Status and Priority|
|Wheel- Rail Interface Study||2006||Implement a new wheel profile with a 70-degree flange angle to replace the current wheel profile with a 63-degree flange angle.||WMATA has requested and received a proposal from TTCI [Transportation Technology Center, Inc., a research and test center owned by the Federal Railroad Administration] to conduct a wheel profile performance test to validate the recommendation and to begin a pilot test implementation.||WMATA received CAF's [Construcciones y Auxiliar de Ferrocarriles, an equipment manufacturer] concurrence to change in profile and will be preparing an ETP to test modification on two 5000-series cars to do a comparative evaluation. After three months of satifactory operation WMATA will extend the test to additional cars before making a decision on an EMI for 5K fleet-wide implementation. ETP will start 11/30/2008. |
2/06/09 -- In February 2009 a pair of 5000 Series railcars will be prepared for testing the new profile. After satisfactory operation WMATA will extend the test to additional cars. 5K fleet-wide implementation is scheduled for the beginning of FY 10.
7/27/09 -- An ETP has been prepared and approved to test the change of the flange angle of 5K cars from 63 degrees to 70 degrees. Calculations support this change to address slow-speed derailments. Currently, a shortage of 5K trucks with full wheel flanges are hindering the start of this test. It is expected that the test will be initiated out of WMATA's West Falls Church S&I [Service and Inspection Yard] within two weeks.
|The new profile should reduce the tendency for derailment. Since it is similar to the current worn-wheel profile, it should also reduce wheel truing [maintenance that keeps wheels properly aligned]. This is the major step in preventing derailments. |
2/13/08 -- TOC approves this CAP with the following changes. The new wheel profile needs to be implemented on the full railcar fleet. The test program is scheduled through 9/2008 followed by implementation. Thus the 12/2007 Estimated Completion Date needs to be changed. TOC will Close when completion is verified. Quarterly status reports are to be provided by WMATA.
|Triennial Audit||2007||The prints in our sample of interlocking locations [intersections in the tracks where trains switch from one track to another] were in the same tattered, ripped, and disorganized condition noted in the Tri-State Oversight Committee's 2004 triennial review.||The Infrastructure Renewal Group (IRPG) is currently managing the reproduction of interlocking location prints utilizing the engineering services of P2D [a consortium of Metro contractors]. Expected completion in five years.||3/23/09 -- Due to funding limitations the expected date of completion will be extended to 10 years instead of the original completion of five years.||2/1/08 -- CAP is okay.||Yes||6/1/18||Open-2|
|Triennial Audit||2007||The prints in our sample of traction power substations [which supply power to the electrified third rail, which powers the trains] were in the same tattered, ripped, and disorganized condition noted in TOC's triennial review.||TSSM [Track and Structures/System Maintenance] and CENS [Chief Engineer, Systems] have agreed that the interim, appropriate measures will be taken to get the drawings in an acceptable state until replaced. These measures will include updating, page replacement, lamination and installing hardware and protective enclosure for proper storage.||Status update: Due to the ongoing upgrades of the 66 traction power substations, CENS and TSSM have agreed to get the Traction Power drawings in an acceptable state by 7/1/11.||2/1/08 -- CAP is okay.||Yes||7/1/11||Open-2|
|Accident Investigation, Woodley Park||2004||Operations coordinates with Safety and Risk Protection and the Office of Labor and Employee Relations to enter into discussions with the Unions, representing WMATA employees, to consider the establishment of "Hours of Service" for operating personnel.||Will implement contract requirements of affording employee eight continuous hours off in a 24-hour period.||12/8/09 -- WMATA has presented to the union a proposal for ten hours uninterrupted rest.||9/12/07 -- The 5/21/07 submission postpones addressing the finding.

|Response to NTSB findings re: Woodley Park||2004||Either accelerate retirement of Rohr-built railcars [1000-series cars, the system's oldest], or if those railcars are not retired but instead rehabilitated, then the Rohr-built passenger railcars should incorporate a retrofit of crashworthiness collision protection that is comparable to the 6000-series railcars.||No corrective action. |
12/8/09 -- The Authority will conduct an evaluation of 1000-series railcar crashworthiness including engineering analysis and testing to confirm the analysis.
|10/2/07 -- WMATA does not plan to do a heavy overhaul on the 1000 series. The 1000 series railcars will be replaced with the 7000 series railcars which design has already started. Constraints of a tax advantage lease on the 1000 Series cars requires WMATA to keep them in service until at least the end of 2014. |
11/21/08 -- WMATA requests CAP be closed by TOC. WMATA does not accept the finding, therefore no action is required. Documentation will be submitted for closure 11/24/08.
07/20/09 -- WMATA submitted copy of Booz Allen Hamilton report "WMATA Rail Vehicle Underframe Strengthening Retrofit Feasibility Study" to TOC. WMATA recommends CAP closure.
|2/13/08 -- WMATA should send TOC a letter stating that a request had gone to NTSB related to the 1000 series railcar for which no response was provided. |
