GFT&RS provided trackwork inspectors that were responsible for initial layout and final assembly of the low-restraint, direct fixation (DF), two track main. The project used the "top-down" method of construction. The project included one No. 5 DF single crossover and one No. 8 DF double crossover. The design allowed for a final offset alignment in order to maintain revenue service until cut-over was performed during a nine-day track outage. Nine existing bridge spans were demolished and replaced with new spans connecting to the revised alignment and structures. The new spans included the No. 8 DF double crossover. On-site field support was provided 24 hours per day during the entire nine-day outage to assure the railroad would be put back in service as soon as possible and within the work window.

Our firm provided detailed construction support
services for this project. Our work consisted
of supplying construction inspection services
for trackwork, signal work and oversight for
construction of the platform canopy for the new
station stop.
The No. 8 double crossover was initially assembled
and constructed off-site and inspected for
conformity. The special trackwork was then disassembled,
trucked to the final location, and reassembled
during the track outage.
