People Movers-Comprehensive Engineering Services

LM Transit has extensive design, engineering, and construction management experience on People Mover Systems.  Our experience includes planning, conceptual, preliminary and final design, detailed engineering, project and construction management, inspections, and testing/commissioning for all people mover subsystems. Our experience includes guideway foundations and structure, guideway switches, stations, integrated stations (into existing buildings), control centers, operations/maintenance facilities, power rail, power distribution, communications systems, passenger vehicles, maintenance and specialty vehicles, ergonomics and man/machine interfaces, and fixed/moving block/CBTC train control systems.  Many of our designs have been completed with three dimensional computer modeling, simulation, visualization, and animation.  Our firm has also worked on the research and development of transit technologies including mag-lev and people movers, with primary focus on vehicles, guideway, switches, winterization, and power rail design.  Our people mover experience includes airport systems, downtown people movers, monorails for convention centers and theme parks, corporate business parks, resort developments, colleges/universities, medical centers, and national parks. We have worked on 11 people mover systems which have been built or are under construction, as well as system planning and conceptual/preliminary designs for more than 45 additional people mover systems.  Our services include:

Rail Transit & Bus System - Communications

Our rail transit and bus experience includes light rail, commuter rail, heavy rail/subways, and city/regional bus systems. This experience includes primarily communications system planning, communications engineering, information systems/information technology services, and systems integration. We have worked on more than 20 transit systems and line extensions that have been built or are currently under construction.  We are a leader in implementing state of the art, open architecture, digital broadband data, audio and video communications systems. These systems utilize Gigabit Ethernet, Synchronous Optical Networks (SONET), Asynchronous Transfer Mode (ATM) switches, fiber optic and wireless communications backbones, Ethernet enabled station and remote devices, Ethernet access for serial data devices, user friendly man-machine interfaces, and ergonomically friendly control centers. Our broad range of transit system experience gives our firm the unique ability to understand the interfaces to all transit subsystems in the field, and as part of central control software and the man/machine interface.  Our goal is to assist transit system operators in improving service to their customers by providing information to passengers and improving on time performance of transit systems.  Our communications engineering services include:
