Commissioners approved the award of a contract worth $60 million for the purchase of 120 low-floor, clean-diesel buses for delivery in 2010. Commissioners decided to delay the expansion of the TTC’s hybrid bus fleet as a result of defective lead-acid batteries and chose to go with clean-diesel buses to ensure ridership growth demands are met in the short term. The 130 hybrid buses scheduled for delivery in 2009 will be equipped with new lithium-ion batteries. The TTC is also working with Daimler on a solution to retrofit the current fleet of hybrids with lithium ion batteries.
