Revisiting CTA’s Hydrogen Buses

The field tests of the fuel cell buses at the Chicago [Illinois, U.S.A.] Transit Authority are yielding some valuable information for the next phase of development. The refueling process has been simplified, allowing buses to be filled more quickly. Drivers have reportedly enjoyed the performance and the acceleration of the vehicles. Mechanics have been adapting well to the new technology with the help of extensive training and detailed manuals.

The only major change that has been implemented since the buses started running was to change from a fan to a water cooling system for auxiliary motors to maintain the temperature in response to the hot Chicago summers. One of the buses required minor repairs after a mild “fender-bender” in the garage. All other systems have been running exceptionally well and routes have been serviced without delays.
