All Aboard Arrow’s Maintenance Facility

August 31, 2021

As preparations are made for the much-anticipated launch of the Arrow line service in 2022, much of the behind-the-scenes work will take place at the new Arrow Maintenance Facility, under construction in the City of San Bernardino.

Several SBCTA staff toured the state-of-the-art facility recently and were able to see just how far this critical part of the Arrow project has progressed. The building features two maintenance bays, a maintenance pit, staff and crew office space, a lunchroom, machine shop area and material storage.

The Arrow line will launch as a nine-mile connection between Redlands and San Bernardino, featuring low-emission Diesel Multiple Units (DMUs) and, eventually, hydrogen-powered Zero-Emission Multiple Units (ZEMUs). The cleaner, more efficient ZEMU train will be the first-of-its kind in North America and among several innovative transportation solutions being introduced by SBCTA.

Along with the West Valley Connector bus rapid-transit system, the planned zero-emission Ontario Loop tunnel project, and the proposed higher-speed rail system from Las Vegas to Rancho Cucamonga, the Arrow line is helping to establish San Bernardino County as the future of transit in Southern California and beyond.
