Many Metro buses currently in revenue service are not able to maintain adequate revenue service speed over the soon to open High Occupancy Vehicle (HOV) lanes over the Sepulveda Pass. These existing buses could also not maintain adequate revenue service speed over the Sepulveda Pass if the HOV lanes were at some point converted to Express Lanes. Therefore any Metro bus service operated in these lanes, now or in the future, requires exploration of higher power buses that would be able to sustain higher speeds through this corridor. Metro can explore options for higher horsepower configurations for existing transit vehicles that Metro could use over the Sepulveda Pass or in other HOV/Express Lane locations. Ideally these higher power buses should be able sustain highway speeds (50 mph+) even at 2 to 5 percent grades. Metro staff is aware of alternate propulsion system configurations that may be better suited to operating on grades than those currently used in Metro’s bus fleet. The current predominant Metro bus engine is the Cummins-Westport ISLG 8.9 liter engine. For standard buses, this engine usually operates at 280 horsepower and 900 pounds of torque. This engine has an alternate configuration available in a 320 horsepower configuration with 1,000 pounds of torque, and this higher horsepower is estimated to allow buses to maintain speeds over the Sepulveda Pass in the 45 to 55+ mile per hour range. Cummins-Westport and Doosan both now offer larger displacement 11- 12 liter CNG engines that could potentially allow even higher speeds (55-65 mph+) over the Sepulveda Pass. Additional engineering work is still needed to determine whether these larger engines could feasibly be retrofitted into current transit bus configurations.
