I hope y'all remembered this bus from the 90s it's the 1998 Orion VI CNG!
The TTC awarded Ontario Bus Industries a $37.7 million contract at the beginning of 1994 for the supply of 100 of their new low-floor buses. The TTC had previously purchased the low-floor Orion II, but the new 40-foot Orion VI would be used in conventional service. This was a welcomed decision from the elderly and disabled community. The Ontario Government announced the previous year that all buses purchased in the province would have to be wheelchair accessible.
The first of the new buses was expected to be delivered in September 1994 with all 100 in service by the end of 1995, however, delays in production soon mounted. A prototype vehicle was delivered to the TTC in July 1995 for testing. It was used in service on the 7 Bathurst and eventually returned to Orion. In an attempt to expedite delivery of the new buses, half of the order was built as lift-equipped high floor buses in 1996. All of the low-floor Orion VIs were finally delivered by the middle of 1998.
In September 1998, the TTC pulled all 50 buses from service after they realized that the buses were being overloaded. They were worried that this could lead to wheel failures. A stronger wheel rim was sourced to rectify the problem. At the same time, the TTC also had to replace deficient steering arms after Orion gave notice of the problem. The buses returned to service in early 1999. The fleet had bike racks installed in 2005.
They were based out of Wilson Garage on routes 7 Bathurst, 29 Dufferin, 47 Lansdowne, 98 Willowdale-Senlac, 105 Dufferin North, 161 Rogers Rd and 196 York University Rocket.
Since these buses were too difficult to convert these buses into diesel powered buses, these buses are retired between 2005 and 2006 and this is currently the last time that the TTC have CNG buses. May these buses (and all CNG buses) RIP :'(
