ISE Receives Order for 25 Gasoline Hybrid-Electric Drive Systems for Long Beach Buses

ISE Corporation (ISE) recently received an order from New Flyer of America (New Flyer) for 25 gasoline hybrid-electric drive systems to be applied in 40-foot buses. This new order will increase Long Beach Transit’s fleet of buses powered by ISE hybrid drive systems from 62 hybrid buses to 87 hybrid buses.

This order is part of the Montebello Consortium program initiated last year for the purchase of 150 gasoline hybrid-electric 40-foot buses. (Earlier post.) This is a Federal Transit Administration pooled procurement program that provides 90% Federal funding to participating agencies.

ISE’s ThunderVolt gasoline hybrid drive system was certified as an alternative fuel system by the California Air Resources Board (CARB) in November 2003. More than 100 of these hybrid systems are already in revenue service in various California cities, including Long Beach, Orange County, Norwalk, Montebello, Gardena, San Bernardino, and Fresno. The Long Beach Transit gasoline hybrid bus fleet has exceeded 5 million miles of total revenue service.



Long haul trucks can put on 200,000 miles per year and I would not be surprised if transit city buses put on 100,000 miles per year. Buses and trucks cost a lot and they need to be in service to pay back. That being the case, the fleet might turn over more rapidly, allowing new technologies to be adopted more quickly.

In my experience in public transit the buses I drove averaged around 30,000 miles per year before the introduction of evening service. I would doubt that any public transit bus would run more than 50,000 miles per year. While 18-wheelers spend much of their day on the Interstate transit buses are rarely driven over 50 mph and the average route speeds are 15 mph. Also on any given day about 20% of the buses were in the shop and another 20% should be.


Good info. The "should be" part is the maintenance that does not get done as often as it should. That being the natural order of things, the simpler and less maintenance the better.
