The project includes removing and installing new rail, 29 track switches and more than 62,000 concrete ties. Crews also will spread 99,000 tons of rock ballast to ensure a stable roadbed and renew the roadway surfaces at 14 crossings.
Union Pacific will use a modern track renewal train, the TRT 909, which installs rail and concrete ties in one pass. The TRT can install up to 5,000 ties in a 12-hour day. The track renewal train consists of approximately 30 rail cars, with each car capable of carrying 210 concrete ties.
