It seemed like we were getting really close last month, but we hit a snag when a “vital logic” programming issue was discovered during a field test. Capital Metro has issued its September progress report, pasted here.
CAPITAL METRORAIL PROGRESS REPORT – SEPTEMBER 17, 2009
Capital Metro appreciates the opportunity to keep the community informed about our progress with the MetroRail Red Line project. Since the last report, we have identified the remaining actions we need to complete to open the line. We are coordinating the resources needed and developing a timeline.
Milestones Completed Since August 19
- Capital Metro and Veolia Transportation enlisted the services of a systems engineering firm to facilitate and coordinate final system integration tasks and resources required to open the line.
- Completed relocation of train detection equipment.
- Federal Railroad Administration (FRA) regional and national teams conducted a site visit Aug. 24-27, and identified a “vital logic” programming issue during field testing.
- Initiated compilation of system integration documentation requested during FRA visit.
- Conducted thorough Hazard Analysis/Risk Assessment. Key issues identified include:
- Programming – Modifications are needed to computer programs at the control points in the field to address the vital logic issue as well as other issues identified in the assessment process.
- Processes – Develop and implement changes to some processes for addressing issues.
- Testing – All program changes will require testing at each site to ensure that the system is functioning as intended after the programming design change.
- Validation – Once the programming changes are made and the individual locations are tested, we will test the integration of the entire system.
- Documentation – The functional specifications, or system integration, will be documented.
All teams involved in the Hazard Analysis/Risk Assessment will meet next week regarding resource coordination, cost estimate and timeline for the key issues listed above that need completion. Capital Metro will continue to update the Board of Directors at its monthly meetings and will have another progress report to the community in October.
