LTK-designed railcarTransforming Caltrain from diesel to clean electric. 

The Bay Area’s growing economy has led to the agreement to develop a blended system of Caltrain and high-speed trains sharing the same tracks and serving the Peninsula. Caltrain has undertaken a modernization program, including the first modern electrification of an operating commuter rail corridor in the United States, and the replacement of most of Caltrain’s diesel fleet with state-of-the-art bi-level electric multiple units (EMUs).

LTK was chosen for its deep knowledge of the transit vehicle industry and close familiarity with Caltrain’s operating environment. Our team has prepared and released a technical specification and RFP and over the next five-plus years, will evaluate and select a carbuilder; and oversee the manufacturing, delivery, testing, commissioning, and warranty support of the vehicles.

With LTK’s guidance, Caltrain has updated its Federal Railroad Administration waiver allowing for non-compliant EMUs to run comingled with its diesel locomotive hauled passenger fleet. The goal is to remove the requirement for temporal separation from freight service in the original waiver. Caltrain released a RFP in 2015 that ensures a vehicle design that will allow for platform-sharing between the agency and the California High-Speed Rail Authority’s future service.
