Document Description
The Southern California Regional Rail Authority (SCRRA) is proposing the Marengo Siding Extension Project (Project) to upgrade Metrolink's current regional passenger rail services along its existing San Bernardino Line. The Project includes new rail infrastructure that would be constructed almost entirely within SCRRA’s existing rightofway (ROW) in the City of Los Angeles, with a small portion (approximately 20 linear feet) extending into unincorporated Los Angeles County. The Project would extend the existing Marengo Siding by approximately 3,325 feet east, resulting in a total siding length of 10,250 feet. The Project would maintain the main track in its existing location and construct the new siding track to the north. The proposed siding extension would terminate at MP 3.1,?just west of where the railroad ROW narrows to 20 feet in width near the Fowler Street curve. The Project would require the following improvements: Grading along the guideway Installing approximately 3,325 feet of new siding track Installing new retaining walls Installing new pier protection walls for overhead structures Replacing ROW fence Installing a new turnout Removing existing signals and signal houses Installing new signals and signal houses Installing a new signal tower at MP 3.1 The Project would also involve the protection-in-place of existing utilities, including existing drainage structures, or relocation where utility structures conflict with the proposed alignment. Project construction is expected to begin in 2022 and would continue for 12?months.
