The TTC’s supplementary agenda for this week includes a report on the settlement of negotiations with Daimler for the problems with the hybrid bus fleet. Parts of this report are confidential, but the main items of interest for system users are in the public report.
- The existing fleet of hybrid buses will be converted from lead acid to Lithium-Ion batteries. This is expected to greatly improve reliability and to reduce fuel consumption by about five percent due to the much lower weight (4,100 vs 1,000 pounds) of the batteries. (The TTC quotes the weight in pounds.)
- The 2009 bus order for 130 hybrids will remain in place.
- The optional 2010 bus order for 120 diesels will proceed. It should be noted that supplementary Federal funding for “green” bus technology is not guaranteed into 2010.
- Due to the larger than expected number of vehicles required both for construction projects (e.g. St. Clair) and to compensate for poor hybrid reliability, 52 “retirement-eligible” GM buses will undergo a life extension. This is expected to add 2 to 3 years to their life. Buses now out of service will be the first to go through this rebuild so that the active fleet is not further depleted. This project will cost $3.5-million or about $65K per bus.
From a budgetary point of view, the total spending remains below the original Capital Budget mainly due to the savings on diesel versus hybrids on the 2010 bus order.
