Recent Work Performed by TCS

BACK

Sound Transit / BNSF - Seattle, WA
TCS is currently completing work designing the extensive resignalization of the 50-mile double and triple track between Seattle and Tacoma. In addition, TCS designed, manufactured and programmed the fiber communication transfer panels and provided extensive field support on all 31 cutovers to date. TCS has engineered and programmed many Temporary Interface locations to link the new VHLC locations to the existing pole line locations during most stages of this project. TCS also compiled cutover record books containing all location plans by stage, project overviews and cutover summary task lists. TCS engineers are continually on-call and available to answer questions and troubleshoot whenever needed.

BNSF – Norstar Corridor Commuter Line - Minneapolis, MN
TCS performed all preliminary signal design engineering for the NorthStar Corridor Commuter Line project. The NorthStar project involves the creation of an 82-mile transportation corridor from Minneapolis to St. Cloud, MN. The project scope included staging plans of construction phases with tie-ins to existing signal facilities, specific plans for 30 crossings and 17 unique control points. TCS also provided preliminary engineering profiles for 15 mitigation points. TCS conducted field surveys and provided necessary material lists by location. TCS has been recently contracted by BNSF to provide final engineering design for the 40-mile NorthStar Commuter Rail System to be installed between Minneapolis and Big Lake, Minnesota.

Seattle Sound Transit - Lakewood toTacoma Commuter Rail, Tacoma, WA
TCS recently completed final engineering for the 10-mile Lakewood toTacoma Commuter Rail project. The project included 7 control points and 18 grade crossings with automatic horn systems and quite zone circuitry. The wayside control system includes fiber optic technology. TCS wrote comprehensive specifications, prepared detailed cost estimates and staged construction plans.

BNSF - Chicago, IL
TCS has designed and programmed the continuing upgrade of this triple track CTC, replacing large interlockings at Cicero, Congress Park, LaVergne, Lisle, Kedzie and Western Avenue. The new system employs fiber optic links and one-microprocessor-per-track to enhance survivability and maintenance. This territory has required that TCS engineer extensive railroad crossing revisions and TCS engineers are routinely on-site to provide field support for in-service cutovers.

Sarajevo, Bosnia
TCS was contracted by International Procurement Corporation to assist the Bosnian Railways in specifying and procuring a new signal system. As signal systems consultant, Lee Kisling surveyed the rail system, created design specifications and provided expertise and recommendations in the procurement bid process.

Port of New Orleans - Florida Avenue Bridge
TCS designed, wired and installed new radio-linked signal and bridge detection systems. Providing turn-key service, TCS designated and procured all signal material and equipment needed, and TCS' construction crew completed the 7-stage construction project in New Orleans over the course of 2-1/2 years. TCS is a licensed contractor in Louisiana.

BNSF-Minneapolis, MN: University Avenue
This total rebuild used multiple vital processors to control seven mainline crossovers, four power
turnouts and signals on four main tracks. TCS pioneered the "Virtual Cutover" concept here.The new interlocking was installed in full revenue service in only 26 hours.

BNSF- Kent, WA
TCS created detailed engineering drawings for this high-density control system consisting of ten grade crossing systems with spread spectrum linear radio network communications to supply downstream activations.

BNSF-Burlington, IA: Burlington Bridge
TCS performed site evaluation and prepared extensive preliminary design drawings to guide complete control system replacement, including detailed material lists. The preliminary design documents create the foundation for cost estimates in this joint effort between the BNSF and the U.S. Corps of Engineers.

BNSF-Minneapolis, MN: Re-signalization of Midway Subdivision
TCS engineered eleven vital processor-based interlockings and the coded track locations that interconnected them, including vital software tested in our laboratory. This territory included numerous crossing upgrades, electric locks, and intermediate signals. TCS created temporary phase-in plans and performed extensive field service.

BNSF-Vancouver, WA
TCS engineered six complete vital processor-based interlockings, including two railroad bridge control system replacements, employing vital radio links across open water channels. TCS designed two bridge control consoles and prepared in-service test documents.

Montana Rail Link-Laurel, MT
TCS engineered vital control equipment, wired an 8x10 bungalow and two VHLC racks, modified a crossing system and designed a coded track/line circuit interface. TCS engineers prepared cutover documents and were on site-to assist during installation.

American Systems Technologies-Seattle, WA: Port of Seattle, Terminal 5 Expansion
TCS designed this all-new yard control system using vital processors at six sites. This system had
elaborate blue flag protection zones initiated from three different control sites.

BNSF-Pasco, WA
TCS designed seven miles of new double track signal equipment including six interlockings. In addition, the Pasco Yard Expansion required four non-vital code replacement HLC units and customized local control panels.

BNSF-Prescott to Coon Creek, MN
TCS engineered and programmed 23 non-vital replacement code systems.

CSX-Boyles Yard, Biringham, AL
TCS designed the new radio/PLC to existing relay-based NX interface on this yard control system upgrade.

Canadian National-Ft. Francis, Ontario
TCS engineered the automation of two remote bascule-type railroad bridges, providing a complex PLC interface to the signal system and the new hydraulic bridge motors. TCS wired the cases, built the new control console and was on-site for commissioning.

CSX-Mobile, AL
TCS engineered new control circuitry with PLC and proximity detector technology on three railroad bridges.

BNSF-Portland, OR
TCS performed on-site survey and created detailed preliminary engineering proposals for replacement of five miles of double track, including three major interlockings and a new control system for the Willamette River Drawbridge. After the proposals were approved, TCS engineered and provided software for this entire project.

BNSF/Amtrak-Chicago, IL
TCS designed circuits and prepared software for a supervisory control rack at Union Station. The
redesign included new coded track control through downtown Chicago and new circuitry at the BNSF largest interlocking: Union Ave. Interlocking.

BNSF-Cascade Tunnel between Seattle and Wenatchee, WA
TCS replaced a relay-based control system with vital processor controls. This system controls critical tunnel fans, vents, doors, and signals. It has four distinct operating modes, including "fully automatic".

BNSF-Hauser, ID
TCS designed and created software for the mainline entrance/exit to a proposed fueling facility,
including remotely linked vital processors to handle six main tracks and eleven power switches.

BNSF-Kelly Lake to Brookston, MN
TCS designed prototype software for the deployment of Microtrax programmable coded track through fifty miles of the remote Iron Range railroad.

Canadian National-Montreal-Wellington Yard
TCS programmed two large interlockings with Alstom/GRS VPI equiptment and five interlockings with centracode units for this fully signaled rail yard.

BNSF-Everett, WA
TCS designed and built new operator control consoles for two moveable bridges and engineered multiple VHLC equipment to control these sites. TCS also engineered and created software for the PLC-Proximity Detection system on both bridges.

Canadian National-St. Hyacinthe Subdavision
TCS engineered and programmed six interlockings and the coded track locations interconnecting them using Alstom/GRS VPI and Genra Code equiptment. Temporary phase-in engineering was also provided to meet cutover planning requirements.
