Scope of work: The project entailed the signal design, software, communication design, manufacturing of train control cabinets and field commissioning of a double crossover, single crossover, intermediates utilizing the VPI with interface connections at tie-in locations utilizing the Sicas7. The project was under extremely tight timelines as the project had a direct connection with Superbowl LII for the purpose of stacking trains on pocket tracks as well as decreasing headway times to allow for more trains.
Scope of work: The project entailed eighteen locations on a traction power railway, control points and double crossovers tested and commissioned. Project started took (9) months of testing. DAI performed grounds testing, foreign current, power distribution, all locking tests, all associated static tests as well as dynamic tests. DAI had supplied (4) Engineers for the entire duration of the project. The project utilized Alstom VPI microprocessors with overlay track circuits and 5F switch machines.
Scope of work: The project entails one of the most complex signal systems in the industry. DAI’s scope functions include the oversight of signal system modifications, pretesting and review of interlocking software as well as test procedures. The project entails over 500 system routes through the entire project.
Scope of work: The project entailed the design and materials supply of a signal system. DAI’s function has included design through commissioning of the signaling system.
Scope of work: The project entailed the reconstruction of the Pier. Balfour Beatty provided all of the field construction forces for the project. DAI provided construction oversight, site specific work plans and cut-over plans. DAI also performed all of the testing and commissioning of the system into services.
