The CNG tanks were placed under the bus in the high floor buses. The design of low floor buses doesn't allow for tanks to be placed under the bus due to space restrictions and is why the roofs have a "hump" now.
The high floor Orion V CNG had its tanks on the roof. Not under the bus. Our Low Floor Orion VI doesn't have them on the roof, so they must have secret hiding places under the bus!

Strange looking bus, is that an A/C unit on the roof ?
I worked at the old HSR bus station on king and wentworth, and then the new place further north on wentworth, in my job as security guard.

Yeah it is. Its where the Natural Gas does it's thing in powering the bus.

That is the Compressed Natural gas on the roof, if you looked under the "caps", you will find metal cylinders, that hold the CNG. :)

LOL! I was thinking about the Hybrid buses.

That's the fuel tank. The place where the natural gas does its thing in powering the bus is called the "engine".
