Safety Recommendation Details

Safety Recommendation R-01-028
Details
Synopsis: In 2000, the MTA experienced two similar accidents in the same location just 6 months apart. Both accidents involved the failure of an MTA LRV train to stop at the designated stopping point at the Baltimore-Washington International Airport Light Rail Station (BWI Airport Station). In both cases, the train struck a hydraulic bumping post apparatus at the end of the track. The Safety Board's investigation of the two accidents indicated that, although the direct cause of each accident was different, aspects of the MTA rail transit operation common to the two accidents influenced both their outcomes. Consequently, the Safety Board developed a special investigation report to address the safety factors affecting both accidents.
Recommendation: TO THE MARYLAND TRANSIT ADMINISTRATION: Install, on all your light rail vehicles, independent event recorders that record and retain the most recent 48 hours of data, store data in nonvolatile memory, and have a back-up power source that would enable the entire recording system to function if electric power is lost to the car.

Response: We last received a letter from the MTA regarding this recommendation in November, 2004. At that time, the MTA had begun drafting a technical specification for adding event recorders to all of the LRVs and the Metro subway railcars. Safety Recommendation R 01 28 was classified OPEN—ACCEPTABLE RESPONSE in April 2005 pending the MTA’s installation of the independent event recorders.

Date: 4/1/2005
Response: The Safety Board notes the MTA has begun drafting technical specifications for adding event recorders to all LRVs and metro subway railcars. The expected completion date of the technical specifications is March 2005, at which time a funding request will be developed. The Board also notes that the MTA has added wayside data recorders to the new Automatic Train Protection (ATP) system and upgraded the video cameras facing inward on each end of the LRVs to add capacity and an uninterruptible power supply that will keep the equipment operational for an extended period of time after a power outage. Pending MTA's installation of the independent event recorders as described in Safety Recommendation R-01-28 on all your LRVs, the recommendation is classified OPEN -- ACCEPTABLE RESPONSE.

Response: Letter Mail Controlled 12/6/2004 9:24:36 AM MC# 2040704 - Lisa L. Dickerson, Acting MTA Administrator: After analyzing the technical challenges and costs, the MTA has begun drafting a technical specification for adding event recorders to all of the Light Rail Vehicles (LRVs) and the Metro Subway Railcars. The expected completion date of the technical specifications is March 2005, at which time a finding request will be developed. In addition, the MTA has placed at each end of the Light Rail Vehicles viewing cameras, which are used for investigative purposes. An Automatic Train Protection (ATP) system was also added to provide extra safety. In addition, wayside data recorders, which track the signaling system, are also part of the ATP system. Also, the VHS tape drive was replaced with a removable hard drive and an Uninterruptible Power Supply (UPS) was added to keep the equipment operational for an extended period of time after a power outage. Your concern in resolving this issue is greatly appreciated. Should you require any additional information, please contact Mr. Ronald Keele, Executive Director, MTA Office of Safety and Risk Management at 410-454-7141.
