The county transportation authority’s description of the Metrolink Arrow focuses on their designation as DMUs (‘Diesel Multiple Units’) which are smaller, more efficient, and cheaper to operate than Metrolink’s standard locomotives.

The design was chosen to fit with the increasing need for both expanded local service between Redland and San Bernardino, and for connecting Redlands with the larger Metrolink trains that run from San Bernardino to LA. The trains were built in Salt Lake City, UT by Stadler, a Swiss company with an 80 year history of building railroad equipment.
