In fairness though, it doesn't help it doesn't have any reasonable spares so they get flogged out every day no doubt some day with minor faults. 

It's similar to Ashington and their Enviros.

The original Pronto B7TLs seem better reliability wise! Those B5TLs need to come off given they could barely hack two years on the X9/X10. X70/X71/X72 would be better suited for them with Enviros covering the evening & Sunday boards on the X30/X72.

But will E400's be able to do those hills. I mean they seem to be handling the A19 okay.

I don't see E400's going onto X21. I just don't think GNE will do it

Good buses the B7's imo. I always think it's a shame they didn't make a 2 axle B8TL for routes that need a bit more rather relying on a turbo. The B5TL is fine for the likes of London though.

For swapping things around, not sure how connected GNE and EYMS are but you'd probably be better sending all the B5TL's and as useless up here B5LH's for their 11 plate Enviros 400's (901 - 910) for the 16/16A and 69 plate Enviro 400 MMC's (911 - 921) for the X5/X15/X21 with 6338 - 6340 filling the gaps. Least then the B5's are doing work which their pretty much designed for especially now the Zebra bid failed.

Howay divint criticse GNE because services are taken out of service

You never critise Arriva in the same way

X7 This week was taken out of service at Haymarket and driven to Jesmond Depot

GNE is targeted because of branded buses

I am more than happy to see every 15-21 days buses taken out of services for a service check they can run

But service 21 you complain about it but wow do some maths

Even think about it Newcastle to Durham and back to Newcastle how many miles is a round trip then work out how.many times in a day it is done

These buses are workhorses from 6am to 11pm

Decide what you want to complain about

Old buses running aka 10yr plus buses or want everything brand new then think about passengers on board and 'cutting services" because you think passengers don't use the service aka 309 310 311 evening services and Coast road as you deem so many passengers use it

Wake up and smell the coffee

I hate to break it to you but buses are designed to run from 5-6 till 11. THe reason GNE is "targeted" is because there branded buses are branded to a route whcih they are never on because they are always off. Why brand a bus if its never going to be on the route. The X21 might aswell be called Voyager X21 not Xlines X21. 

Reliability of the B5's are a constant issue and have been since they were bought. I am more than happy for a bus to be taken out of service for maintenance but not 4-5 out of the 7 in ONE DAY. 

Branded buses are another issue entirely you brand a bus to be put on that route [Don't get me started on Consett and Deptford] (I mean the branding doesn't even have route numbers so it can be easy to get confused). And also the Voyagers (15 year old) are much more reliable than 5 year old buses. 

Buses are designed to do 15 years roughly of work, but they just need to be allocated to routes which they can manage. Its like allocating a Cadet to the X10 work daily not going to happen.

Not sure on the work don't see why they'd need too though. Arriva Leeds have a batch and I don't believe they come to the North East.

I believe EYMS / GNE are the same company now though but I'm not sure how closely knit it is in terms of being able to just swapping things. Most the 69 plates would be replaced for the 67 plates though mostly.

Who's criticising GNE for taking buses (that actually were running in the first place) out of service.

Don't want to derail this into North Tyneside again but it's pretty common knowledge there's too many buses along the Coast Road, it's even been mentioned by Dan a few times. If there wasn't such a scrap fight along there and the fares were the price they actually should be then the money made off those routes could be used at GNE / Arriva to subsidise other routes that maybe aren't profitable in the evening and the mess that it is now might have never happened like the 19, 17, 81, 57 (Whitley to North Shields), 51 (Every 30 Mins Briardene area) which have all been butchered to pieces since the bus wars along there. That's the opposite argument.

I can't comment on the Southern depots (Arriva Darlington / Durham don't seem too clever) as it's not my area but GNE are providing the worst service out of the big 3 locally round here so they will get the most criticism from me at least and that's nothing to do with branding. I could criticise Ashington for it's poor buses but there's investment due very soon so it's not really the time and Blyth (my local depot) have very little lost work even known the fleet is getting on now so picking one board on the X7 is nitpicking.

EY are GNE's subsidary and fall under GNE's management. A swap like that would be logical if PVR's matched.

Would you not take the EvoSetis for the X5/X15, or for the 47.

Also 69' Plates don't have tables, wonder if they were moved whether they would be added.

Or because the EvoSetis are low height you could run them on the X70/71/72 leaving some E400 for X30/31/. Allowing for E400's to be on X5/X15 & X21
RE: X21 B5 reliability
It'd be interesting to see actual reliability statistics on the B5s since they've moved to the X21. Without seeing the actual stats, I'd hazard a guess and say that reliability on the X21 has actually gone up. I certainly see less off-brand vehicles on it compared to when the 16 plate StreetDecks operated.

In my view, the issue with the 'reliability' is probably less down to the vehicles being less reliable, and more down to the vehicles being down for longer due to issues getting parts, which compounds resulting in multiple vehicles being off the road at once, whereas in the past there would just be one at a time, in rotation.

X21 reliability has definitely gone up since the B5's were introduced, but it is still poor.

Tbh it was more thinking about keeping all the B5's together down in Hull / EYMS where arguably they'd be best be. They're good buses on city work hence there's loads in service in London so would be ideal working around in Hull. The EvoSetis are B5's aswell so you'd just be swapping B5's for B5's. 

What comes up doesn't really matter though I suppose with the 69 plate Enviros. More B9's instead of the Enviro 400's could work either really for the 16/16A and have more fleet continuity. Even if it's the older ones so it balances out the age of the fleets a bit or if it doesn't actually need deckers bring some singles instead either.
RE: X21 B5 reliability
In Pyongyang, reliability isn't an issue on any service operated within the city.

Breakdowns, quite simply, don't happen, and when they do, there are series of protocols passengers must observe

Firstly, passengers are forbidden to comment on any aspect of the breakdown as breakdowns don't happen in North Korea.

Secondly, if a breakdown does occur, passengers are required to alight the vehicle and line up in the formation in which they were sitting. An official appears from the ministry of truth and transport to administer instructions and to make sure the first breakdown protocol is being followed.

Thirdly, as breakdowns don't happen in North Korea, passengers are to continue as if the breakdown hadn't happened. This involves taking instruction from the assigned official and marching, in the formation in which you were seated, along the roads and streets of Pyongyang, leaving the parade at the bus-stop in which you intended to alight.

It doesn't matter what happens to the vehicle once you've alighted and have started marching, as breakdowns don't happen in North Korea.

Perhaps such a system should be implemented in the North East to eliminate reliability issues. As you can see, it works well in North Korea.
RE: X21 B5 reliability
Isn't the X21 PVR 9? Without spares in the same spec/livery a missing B5 is always going to be noticeable - and with a reasonably high vehicle requirement it's always likely that one will be off the road.

MOT preparation, vandalism, regular servicing inspections, and accident damage repair are all reasons a vehicle could be off the road relatively long term without being linked to actual vehicle reliability. Couple that with apparent increased waiting times for parts, and the B5s being oddballs in the GNE fleet, it means that minor defects can potentially keep them off for longer than on more common vehicle types where there are possibly more parts kept in stores.

That said, realistically a PVR of 9 should probably have a branded spare, and I agree it's not a good look when you're trying to push the new X-Lines brand in the #betterthanever campaigns when there are Voyager deckers (that aren't even clearly GNE buses - especially with the "contract bus hire" taglines which gives the impression they've been hired in) operating the service on a regular basis. Have the Voyager B9s had USBs fitted, or seat retrims?

Nope, but they do have seat belts, which you can stretch across the gangway and click into the seats opposite thus creating your very own VIP section towards the rear of the bus.

The fact that the two generic X-Lines 'Spares' now form part of the PVR for the X21 really does show how little they seem to care about it now. 20% of the allocated vehicles don't meet the promised spec of the route (assuming they're still promising tables, which they were last time I checked), so should I really expect anything better from whatever they have laying around to shove on the route?

I honestly wouldn't mind if the Voyagers were the same spec, but they're not. The seats, while tolerable, aren't the most comfortable for a 2 hour journey, there's no USB/sockets, no tables. I believe there's NSA, but it doesn't always work.

No, not in the slightest!

Citaro seats are the absolute worst, they have essentially no padding under the leather. I actually didn't mind the ex-bluestar Citaros we had, the seats on those were alright, it's whatever GNE did to them when they refurbished them that ruined them. I used to use Citaros regularly on the 49 and don't recall hating the seats then

The E400 seats are alright for <20 minute journey, but longer than that the lack of support is an issue. Theres too much soft foam and padding in the seat, and not enough hard foam, meaning after 20-30 minutes you've sunk through the soft foam and are essentially sitting on the plastic/metal frame of the seat.

Eyms don't generally operate city only services in Hull. They go out to the surrounding villages. The city roads are very cobwebby in their layout, though, so they will serve main roads like holderness Road and Beverley Road, just like the angel serves Durham Road and the 56 Old Durham Road, before they leave the city.
RE: X21 B5 reliability
Husband was in Amsterdam for Intertraffic, a few weeks ago. They were demonstrating driverless buses. They only take about 8 passengers but would be otherwise perfect for the x21 ¯\_(ツ)_/¯
RE: X21 B5 reliability
So, I did some crude reliability stats based on the info available on Bustimes.
I based it on the number of days that the vehicles were in service over the last 31 days, obviously it doesn't take into account the days were the PVR is reduced (ie. Sundays and bank holidays), but I also did a comparison excluding these days as in theory all vehicles should be in service. If a vehicle was only out for half a day, I counted it as half a day etc.

Of the 67 plate B5s, the average 'reliability' was 79%, or 90% if we only include days with a full PVR
For the B5 spares, the average 'reliability' was 68%, or 78%

It breaks down per vehicle thusly:
6308 - 77% - 92%
6309 - 97% - 100%
6310 - 61% - 72%
6311 - 80% - 94%
6312 - 84% - 96%
6313 - 75% - 88%
6314 - 79% - 90%
6334 - 73% - 82%
6335 - 63% - 74%

In the last 31 days, there have been 6 days where all B5s (including spares) have been in service, 10 days with one out of service, 7 days with 2 out of service, 1 day with 3 out of service, and 1 day with 6 out of service.

6310 has been out of service since the 14th April, but other than that, the longest a vehicle has been out of service was 3 days (with one of those days being a Sunday, so it could well have been out of service due to the reduced PVR)

As a comparison, I picked a new StreetDeck (6369) and E400 (6342) at 'random' (nothing to do with the numbers), with the StreetDeck being 74% reliable, and the E400 being 81% reliable. I couldn't be arsed to do a larger sample of them, so that's probably not that representative.


So, taking all that into consideration, I'd say the B5s are actually, on the whole, fairly reliable on the X21, with most of the issues stemming from the lack of branded spares other than the ones forming part of the PVR. 
If the X21 had 2 extra branded vehicles (like it's supposed to), then there would have only been 2 days in the last month that there would have been non X-lines vehicles

If I have some free time next week, I might calculate the reliability stats on some other vehicle types, maybe not doing a full month on them because I'm lazy, but I imagine checking 2 weeks worth would probably be enough

I based it on the number of days that the vehicles were in service over the last 31 days, obviously it doesn't take into account the days were the PVR is reduced (ie. Sundays and bank holidays), but I also did a comparison excluding these days as in theory all vehicles should be in service. If a vehicle was only out for half a day, I counted it as half a day etc.

Of the 67 plate B5s, the average 'reliability' was 79%, or 90% if we only include days with a full PVR
For the B5 spares, the average 'reliability' was 68%, or 78%

It breaks down per vehicle thusly:
6308 - 77% - 92%
6309 - 97% - 100%
6310 - 61% - 72%
6311 - 80% - 94%
6312 - 84% - 96%
6313 - 75% - 88%
6314 - 79% - 90%
6334 - 73% - 82%
6335 - 63% - 74%

In the last 31 days, there have been 6 days where all B5s (including spares) have been in service, 10 days with one out of service, 7 days with 2 out of service, 1 day with 3 out of service, and 1 day with 6 out of service.

6310 has been out of service since the 14th April, but other than that, the longest a vehicle has been out of service was 3 days (with one of those days being a Sunday, so it could well have been out of service due to the reduced PVR)

As a comparison, I picked a new StreetDeck (6369) and E400 (6342) at 'random' (nothing to do with the numbers), with the StreetDeck being 74% reliable, and the E400 being 81% reliable. I couldn't be arsed to do a larger sample of them, so that's probably not that representative.


So, taking all that into consideration, I'd say the B5s are actually, on the whole, fairly reliable on the X21, with most of the issues stemming from the lack of branded spares other than the ones forming part of the PVR. 
If the X21 had 2 extra branded vehicles (like it's supposed to), then there would have only been 2 days in the last month that there would have been 2 days with non X-lines vehicles

If I have some free time next week, I might calculate the reliability stats on some other vehicle types, maybe not doing a full month on them because I'm lazy, but I imagine checking 2 weeks worth would probably be enough
I wouldn't say the B5s on X21 are any more reliable/unreliable than most of the other modern stock, there's always going to be times when a bus needs to be off the road whether that be for maintenance or has suffered some other issue (eg vandalism or something like a passenger taking ill on board), they're 4 years old now so have certainly been broken in by now.

X21 is quite a noticeable one for stand-ins as there now isn't a dedicated Xlines liveried spare at CLS since the PVR increase (same with X20) and the usual stand ins on the X21 being typically a StreetDeck or a Voyager liveried B9 with the latter not being to quite the same spec as to what's being advertised.

We've just had the two weeks Easter Holidays as well so it's the ideal time to do more work on the fleet when less of the fleet is required.

We don't always know why a trip hasn't ran or has used a different type, some X21's are getting cancelled due to the driver shortage situation.

The city roads are very cobwebby in their layout, though, so they will serve main roads like holderness Road and Beverley Road, just like the angel serves Durham Road and the 56 Old Durham Road, before they leave the city.

I must admit I don't know the routes but the just quickly looking at the routes the Enviro's are generally on they seemed quite urban (56/57/104/154). 

They seem to use the EvoSetis on the longer routes which contradicts what I said in a way but I'll ignore that ?.

Isn't there loads of free buses down there now anyway I've heard they absolutely butchered the Driffield network.
