Title: NX Hybrid 2014
Post by: Daniel541 on January 16, 2013, 01:06:08 PM
Coventry garage could getting some new hybrid buses next year.

I have good suggest:- Former 32/33 should back on the service and Hybrid buses could on former 32/33 route that is most popular from Tanyard Farm/ Tile Hill North to Potters Green/ Bell Green and 32/33 should be Every 7-8min along to Ansty Road. Hybrid Buses would be the best place on 32/33 route!

If hybrids were to come to Coventry my guess will be they would be used on the 13 and the gemini's either transferred to NXWM or used on other services to replace older tridents and alx400.

Never been on a Cov Gemini, I imagine that they're slow compared to WM ones, although ours are slow too, but pick up would be better I imagine.

Seemed much the same when i went on one

Why would they be slower?!?

I think the only difference isn the gearbox, their Geminis are Voith while ours are ZF, also their ALX B7s are ZF and ours are Voith

Yeah basically they sound like our ALX400 B7's and have Voith gearboxes (and happen to be my fave gems in the fleet)! They're still B7TL's so I'd imagine mechanically and performance-wise they are near enough the same as ours. They don't seem noticeably slower though, to me they seem exactly the same as ZF.

Would certainly be interesting to see Hybrids in Coventry but that would probably depend on securing some funding first!

Think about the difference between the first bath of Tridents and the last.

This first pick up a lot slower because of less gears so the revs are very low on each gear change thus slower pickup. The last Tridents, particular the 44** batch, are quicker to pick up.

gearbox's seem to be quite a big thing, look at the Volvo I-shift they make the Volvos just useless! plus the complete terrible joke of a gear box on most older optares!!!

Really I shifts are good on trucks actually the best on the market must be a maintence thing (in house fitters have no clue how to fix them)

None of that is correct

If anything from my experience of WN's Tridents the Y, 51,52 Reg's feel quicker to pick up than the later ones

All of it's correct actually.

The ZF Tridents will have shorter ratios on the gearbox, so all the gears are closer together thus giving higher acceleration thus giving quick pickup.

The Voith Tridents will have longer gear ratios, so it stays in the gears longer, due to them only having 3 or 4 gears. This means they take longer to redline (get to the highest revs possible).

Edit: Having said that, when revving lower, Voith Tridents will be in the prime, with regards to the torque produced so that does balance things more.

Isn't the idea to provide a safe comfortable journey for passengers, not 'Redlining' the b***h?
Fuel economy?
Wear & tear?

Just kidding....they are all slow!!!!!!

And it all depends on how they are set up, what revs they change etc. Engine management systems are clever things. So no, it wasn't all correct

This morning, I have spoken to driver. He say" NXC will get a 15 or more than 15 Hybrid come into 2014!" He believe Hybrid will be on the 13 and He say" 13 route PVR is 9 or 10 including one for peak time and so 3 or 4 Hybrid maybe going on the 6/6A, 16/16A but he not sure about 11/12.

If NXC want keep spare hybrid on the 6/6A, and 16/16A that other E400 (4830-4832 & 4885-4889 will have much on the 11/12 expect sometime on the 10)

And he has confirm of 15 or more than 15 Hybrid will part of 300 order!

And of course the driver you spoke to will be the one responsible for placing orders deciding allocations etc.....

The remainder of the Green Bus 4 which no doubt the NXC bid will have been included in is yet to be announced

And of course it the PVR includes peak time, that's what it stands for. Peak Vehicle Requirement

I haven't, but whilst NX may already know they will get funding, the remainder of the Green Bus Fund 4 is still yet to be announced. I can't see NX buying new Hybrids outright without funding.....
