Southern California Regional Railroad Authority (SCRRA) - METROLINK
MECRail currently provides ongoing, full-time, fully staffed, system-wide, installation, maintenance, and repairs on the METROLINK Rail system.  This is a 420 mile mainline railroad operating under the following traffic conditions:

• METROLINK - 206 passenger trains/day
• Amtrak - 82 passenger trains/day
• Union Pacific/Southern Pacific - 58 freight trains/day
• Burlington Northern Santa Fe - 26 freight trains/day

This program includes furnishing materials, complete installation, testing, and commissioning of all rail signal and communications system upgrades throughout various segments of the line.   Additionally, it includes providing "round-the-clock" signal maintenance that includes data radio, microwave repeaters, fibre optic carrier transmission, two-way radio, telephone, and various Public Address systems.

Burlington Northern Santa Fe Railroad - Stampede Pass C&S Rehabilitation
MECRail recently completed a 150 mile signal system upgrade for BNSF on their Stampede Pass route through the Cascade mountains in Washington state.  The project included the installation of 42 grade crossings, 12 interlockings with switch heaters, 3 slide fences, and 6 hot box/dragging equipment detectors.  All work was completed under traffic conditions; was fast-tracked and completed in a record 6 months - on schedule and under budget.   The particular nature of this project required critical and detailed scheduling and coordination with the railroad, suppliers, and other contractors involved in bridge & structure construction, track rehabilitation, and pedestrian and street traffic movements.   MECRail was a subcontractor on this project working through Harmon Industries.

CSX Transportation Company - Indiana C&S Capacity Improvement Rehabilitation
MECRail currently provides installation supervision, inspection, testing, and cut-over management for this 270 mile "double-tracking" upgrade between Greenwich, Ohio and Chicago, Illinois.  Responsibilities include establishment of monthly, weekly, and daily work plans and direction and supervision of CSXT and subcontractor installation work crews ranging in size from 130 to 150 people.  MECRail is a subcontractor on this project working through Harmon Industries.

Amtrak - North End Electrification Project
This project has been particularly challenging because of traffic frequency and scope requirements.   It sets forth various rules for use of/and access to the rail line and the maintenance of uninterrupted passenger service during the construction period.  The route is divided into 28 blocks which are defined between interlockings on the tracks and vary in length from less than one (1) mile to more than eighteen (18) miles.  Blocks are provided at random times for construction activities while the railroad "single-tracks" around construction crews.  Each phase of construction requires labor distribution, material fabrication and layout, installation, cleanup, punch-listing, and testing.  With limited access, staging, and on-rail occupancy, the scheduling and coordination of these linear operations must be done daily.   Installation of the electrification hardware is depended on the linear progression made by the preceding foundation installation operation during joint block occupancy.   Pole and wiring crews must work closely with foundation installation crews to ensure safety, maximum work windows, limited interference and optimum efficiency during all first pass activities.  To accomplish this, all design issues, conflicts, fabrication and delivery issues, surveys, environmental provisions, installation activities, quality control and assurance procedures, cleanup, and testing have all required precision project management and implementation.  MEC is a prime contractor on this project working directly for the owner in a 50/50 joint venture.

The above examples are representative of heavy-haul rail experience.  Additional experience has been acquired through transit & commuter rail projects that have been completed by Mass. Electric Construction Company (MEC) since the late 1950's  and have totaled in excess of US$1 billion.  Currently, MEC is the largest installer of transit and passenger rail based signal-communications and traction power systems in the U.S.  The company has worked on all major transit properties and has acquired significant knowledge of all major signal & communications equipment and technologies.
