Transportation Project Experience
Representative samples of our staff’s project experience include:

Los Angeles MTA Gold Line LRT:

TEM staff member Marc Knickerbocker was the lead SCADA designer for the Los Angeles Gold Line light rail project. Responsibilities includes design of the RTU communication network and interfaces to traction power, signaling, fire and emergency management system, mechanical and electrical systems. Marc also designed the access control and intrusion detection system.

Maryland Transit Authority P25 Digital Trunked Mobile Radio System: 

This project was a two-way police mobile radio system upgrade from a conventional system to a new P25 digital trunked system. TEM staff member Matthew Wolff was the task manager and project engineer for the production of the RFP and design coordination. The engineering included RF coverage studies to locate the base station repeaters and produce hardware specifications for equipment and system integration.

Regional Transportation District T-REX Design-Build Light Rail Expansion Project:

This project added 19 miles of new double-track light rail; 13 stations, with park-n-Rides at 12 of the stations; adding 34 light rail vehicles to RTD’s fleet; and a new Elati LRT maintenance facility.  TEM staff Jonnie Thomas provided the communications systems design and installation oversight.

Sound Transit, Seattle, Washington Central Link LRT:

TEM’s Marc Knickerbocker is performing construction management services for the communications and control systems for the Sound Transit Central Link Light Rail Project. This involves the retrofitting of the existing Metro downtown tunnel and new construction including the Beacon Hill tunnel. The communication systems include local and wide area networking, SCADA, CCTV, emergency telephones, Visual Message Signs, access control & intrusion detection, and fire system interfacing.

Tri-County Metropolitan Transportation District of Oregon: 

Jonnie Thomas was the agencies Lead Engineer for the design and implementation of the Siemens-Rolm PBX modifications, the Synchronous Network Fiber Optic System (SONET), channel bank system, security systems, digital cross-connect system, Ethernet LAN, PSTN leased line circuits, public address system, audio recording system and Motorola Centracom radio system.

Denver RTD West Corridor Signals and Communications Design: 

TEM performed signals and communications design for this project in the Denver area.  For communications the systems design includes PBX modifications, the high speed IP wide area network, Ethernet LAN, public address system, and PA/VMS system.

Minneapolis Central Corridor Light Rail Line:

This project includes adding 11 miles of light rail and 21 stations in the Minneapolis area. Triunity is providing communications system design. The design includes SCADA, fiber optic network, telephone system, CCTV and passenger information. Lee Denney and Matt Wolff are providing the design engineering services for this project.

Denver RTD Substation Upgrade Project: 

TEM team member John Clem is a key member of the group implementing a change out of the agencies existing Siemens S5 PLCs. The change out includes both existing substations and new substations. A key element in the design is coordinating the change out PLCs with those currently in operation.  John provides PLC and SCADA expertise to the design team.

Phoenix Central Corridor Light Rail Line:

TEM’s Jonnie Thomas is providing communications system design and construction QA oversight of the 20 mile, 28 station light rail corridor in Phoenix. The communication system includes a new SCADA system, radio system, fiber optic network, high speed IP network, CCTV system, emergency telephone system, public address system and variable message sign system.

Denver RTD CCTV Upgrade Project:  

Jonnie Thomas is leading this design effort to design, procure and install closed circuit television at 16 light rail platforms. Included in the design is the conversion of the existing system from an analog based system to an IP-based system. The system will include network video recorders and storage area networks in the wayside communications house, upgrade to the security management system, encoders and twisted pair video transmission.”
