  1. It would appear that the rebuilds are now not getting new rear doors. Could be something simple like the doors are on backorder from flyer or vapor, and will be installed at a later date. Or, they trimmed the budget for some reason. No one ever set that in stone. In regards to finding a new paint supplier, that is likely true. TTC is trying very hard to get away from paint that contains isocyanates. Google it....it's really nasty, toxic stuff, albeit very durable.
  2. Because mount Dennis techs and malvern techs are familiar with servicing them. og and NG hybrids are different under the hood.
  3. 1215 is now a diagnostics and troubleshooting instructional bus for the training department. still residing at malvern for the time being
  4. In that case, likely to reduce the exhaust stink entering the passenger compartment. Fan would also aid in dissipating cng fumes even more. Does it blow in, or out? I'm skeptical of the extra cooling argument, there are methods with the radiator to fix that, if it's an issue. Like: lowering the fan set-point increasing the fan speed (nova has their own proprietary electric fan system, similar to EMP) mods to the radiator itself would involve the manufacturer, and imply that their R&D was flawed. changing the thermostat to a lower setting However, late production Orion IIs, both diesel and cng, had such a fan.
  5. Helps to aid in dissipating natural gas in the event of a leak. Natural gas is lighter than air, and won't come out the bottom of the engine compartment. Also the reason why older high floor buses put their tanks on the roof, even though there was room under the floor for them. Conversely, for propane, the opposite is true. So hypothetically, should a bus be powered with the stuff, the best place for a tank would be under the floor. addition of the vents certainly won't prevent an explosion should a leak occur, but every little bit helps.
  6. Long AND short answer is NO.
  7. ^ this You're an idiot. Go away.
  8. All is true. Except for the 20 minute fix. 20 minutes would be the upload time. They haven't even figured out who the cause is...( Volvo, cummins, wabco, Allison, carrier, hubner,)
  9. They will be wrapped. Albeit in the "new" scheme.
  10. Not anymore.
  11. Everything up to the final 8300 spec'd drum brakes, but I'm fairly certain discs were available as an option by then. Someone who had closer ties to the factory may know better than I. As far as reliability and ease of maintenance, I'd say discs win hands down now. It was a long, long learning curve getting there though. I recall early Rockwell discs on 102dl3 tags were absolutely awful in the late '90s. So much so that mci offered drum conversion kits for the tags at a special reduced cost. the 9200s had discs in the front too, as did all other Orion 6s, ( except OC Transpo, I'm told) and they were problematic. TTC just stayed with the established technology until most of the kinks were ironed out.
  12. "Sharky"- 1786, has been unwrapped.
  13. Disc brakes on all 4 (or 6) wheels has been standard equipment for quite some time now. the entire heavy duty industry is shifting towards them.
  14. All things considered, the elfs were more reliable, but only relative to the friendlies. The blue smoke is extra fuel being dumped into the exhaust to bring up the temperature during DPF regeneration.
