| Description The Westside/Hillsboro Extension involved the construction of 18 miles of light rail double track main line between downtown Portland, Beaverton and
Hillsboro, two miles of paved track in Portland and the Hillsboro central business district and 16 miles on a dedicated right-of-way, including the three-mile West Hills tunnel.
Following the firm's successful work with TriMet on the Banfield Light Rail Project, LTK was selected as TriMet's systems engineering consultant for the Westside Corridor. LTK provided preliminary engineering (PE) and final design and construction management for all systems elements. Service on a one-mile segment has operated successfully since September 1997 as an extension of Eastside MAX, with low floor cars serving the entire 16-mile route. Service on the Westside MAX officially opened in September 1998. All cars are now operational and in service, and are exceeding expectations. As part of PE and in support of the DEIS, LTK performed a Level Boarding Alternatives Study–ultimately leading to TriMet's decision to procure the first modern low-floor light rail vehicles (LFLRVs) in North America. LTK provided services for the following systems elements: 52 LFLRVs, the 75,000 sq. ft. Elmonica operations and maintenance facility including work equipment and special tools, 12 traction power substations, overhead contact system, system-wide duct bank, train control/signal system, train-to-wayside communications (TWC), fare collection and corrosion control. The expansion of service and the addition of a tunnel to the system created more sophisticated systems needs for Tri-Met. LTK's revised scope included: a 15,000-volt distribution system, 30 miles of new fiber-optic backbone communications system, full central control, SCADA, closed-circuit TV, ADA-compliant message boards, PA system and a 900 MHz radio system coordinated with the City of Portland's regional system. The Elmonica maintenance facility was completed in time to take delivery for testing of the first new LFLRV which was delivered in May 1996. LTK provided inspection and testing of all systems and managed the start-up and integrated testing. |

| Description NYCT is in the process of designing and procuring
its "New Generation Subway Cars" for the famed New York subway system. These cars are designated as R142 and R142A cars for use on the ‘A’ Division (formerly the IRT) and R143
and R160 cars for use on the ‘B’ Division (formerly the BMT and IND). In July 1997, the Authority awarded a contract to Bombardier Inc. for the R142 cars and to Kawasaki Rail Car, Inc. for the R142A cars. In December 1998, a contract was awarded to Kawasaki for the R143 cars.
In September 2002, a contract was awarded to
Alstom for 660 R160 cars. Including
exercised options, the total for the procurements is
2,422 cars, with additional option quantities yet
to be exercised.
LTK is providing extensive services for these procurement programs. Key activities
include concept development, preparation of specification and contract commercial
terms, bid evaluation, assisting in developing the contractor selection
process, participating in selection activities and contract
negotiations, and a complete complement of program management, design review and inspection services. |

| Description LTK has been involved with the Tren Urbano Rail System in San Juan, Puerto Rico, since 1996, when we prepared the rapid transit vehicle criteria and specification that was incorporated into the turn-key Request for Proposal. The new system will provide fast, economical, and attractive rapid rail service within the San Juan metropolitan area. The initial system will include approximately 10.7 miles of mainline trackage. The system is expected to be expanded over the next
20 years and will operate using an automatic train control system.
LTK provided the conceptual and preliminary industrial engineering of a heavy-rail service yard, maintenance, communications and administrative. The Maintenance and Operations Facility will serve as the central reporting location for all of Tren Urbano. The $35 million facility includes a Main Building with four through tracks and an administrative/support shop wing consisting of 103,100 sq. ft. In addition, there is a Trainwash/Extraordinary Cleaning building and a Maintenance-of-Way Building. LTK provided extensive design and procurement services for all vehicles. The Tren Urbano vehicle, constructed by Siemens, involves a cadre of international manufacturers. LTK was responsible for making sure that the extensive coordination of all vehicle systems was carried out. As in many recent cars, the HVAC system is a completely self-contained, roof mounted "package", which can be quickly replaced, allowing the car to be returned to service while the units are repaired. A low-power radio link permits the train operator to use PA and radio systems at any time while moving freely about the cab to observe door operation on either side. Styling has been worked out in coordination with an industrial designer to obtain an attractive appearance and upscale image without sacrifice of operational features. Two pilot cars were delivered to the test track in San Juan in late 1999. Because of the necessary time scale for the civil construction included in the turnkey project, there
was adequate time for the pilot cars to be fully tested before final production of the remaining cars. |

| Description In 1967, LTK embarked on a long term program which resulted in the development of the M-Series cars. These electric multiple units (EMUs) have been the workhorses for the Long Island Rail Road and Metro-North Railroad for more than 25 years. In 1998, after assisting with every M-series procurement, LTK was awarded the GEC contract for the procurement of the latest vehicles, LIRR’s M-7 commuter cars. Program management tasks included the
completion of the technical specification and review of contractor and supplier proposals. The firm also was called upon to evaluate alternative configurations for this new EMU car design.
The initial fleets (M-1, M-1a, M-3, M-3a) were developed for the Long Island Rail Road and the Harlem & Hudson Divisions of the Metropolitan Region of Penn Central (now Metro-North Railroad). A total of 1266 of these cars were built. The fleet was enhanced in 1972 by the development of a fleet of dual voltage
EMUs serving reliably in the New York-New Haven region since inception. For the M-2 cars, design improvements were made in the motor suspension, and clean air ventilation was achieved for the first time. The M-2 suspension and ventilation design improvements were incorporated by NJ Transit for the Arrow II and Arrow III cars, and by SEPTA for the Silverliner IV cars. The New Haven "M"-series of complex, high-performance cars operate on both 600 VDC third rail and 12kV catenary power. The more recent M-4 and M-6 cars represent design evolutions incorporating state-of-the-art technology to achieve improved reliability and maintainability. |
