I ride the Flyers very often, they don't all seem so beat and tired in my opinion

now I wonder how a Ride-On C40LF would look restyled, this will be interesting...

The only issue I've seen with Buses "R" Us's New Flyers is the same problem they have with all their 40-footers -- drivers making a 35-foot turn in a 40-foot bus leaving dings, dents, and scuff marks near the rear door where the bus makes contact with streetlights, cars, fire hydrants, and other obstacles.

While NABI had serious problems with the CTA artics (actually a custom order) they are winning business especially in Cali (Santa Monica just ordered 11 BRT artics). But how NABI fares as they wind down the big NJT and LACMTA orders will be interesting.

NABI has also been awarded several small orders for the BRT artics which were probably piggybacked on other big orders.

Hasn't every CNG 60BRT made to date that hasn't been for LACMTA been a piggyback off of the LACMTA order?

I wouldn't say beat and tired, but I would say uninspired. They look nice, but unless you're in the way back those seats suck big time.

I said beat because the exact thing tristan said, Driver error with the turns and etc. But other than that there a nice but of the fleet and would love to see more.

I can see them ordering New Flyers because the current Operations Manager is from SEPTA and has even expressed that he would like to go in that direction.

Oh no!

Speaking of The CNG.......So i recorded this aboard 5914 on the 74 to Germantown, At red lights and stops this bus revved like crazy, does anyone know why it does that... i also know 5804 and 5905 does this.. i ride  5905 everyday home from work on the 76. Does anyone know what causes this? I actually like it though...This big had lots of personality.(sorry for the crappy recording)

It's just a property of CNG I believe - as a gas, not a free-flowing liquid, I think (100% guess) that it doesn't flow as smoothly to the engine as a liquefied fuel would.  I've noticed that this happens in the evenings on some units as the fuel gets lower in the tank -- my guess is that if you have X amount of gas compressed into a space, it isn't as compressed the more it's used and the more space becomes available, meaning it doesn't flow with such high pressure, causing weird idles and strange knocking.

See if this sounds like what you're talking about...especially the HARD knocking as this bus tries to make it up hills.  This was at about 9 PM, probably a good 15 hours or more after this bus was fueled.

I don't know about 5804 or 5905 but 5914's revving is freakin crazy, when i got on the 74 bus going back home one day at Shady Grove Station, and the bus was just idling there for what seemed like forever, it can drive you insane just hearing that same sound for about 5-10 minutes

Hey Im getting a error when trying to click on the link, and u may be right. b/c when ever these buses are doing that its in the early afternoon or late in the evening. and no that sound wouldt drive me crazy...actually prefer to ride buses that sound odd and different makes my ride 10x more enjoyable.

Think it's a DD50G thing?  I don't recall other CNG engines doing that, but of course my experience is limited.

[Tristan]

Nah, WMATA's Orion VIIs buck a lot too, again, in the evening after the fuel pressure decreases.

I'm assuming b/c of the different runs the buses have they get fueled at  different time? b/c in the summer I would always get 5907 on the 59 at the same time at 9:32 in the morning and it would do the same exact thing. At first I thought it was just isolated to the voiths. But I've been on a couple of the 5900's ZF's and the NF's and they done it also...
