Yes it is intended to be. The bus, which I felt was so significant was about to be scrapped. Thankfully I stepped up, saved the bus, restored it and now pay for it's retirement. I hope you find the help you need, good luck ❤

Private plate added by Brylaine Travel. Very common for their buses during this period.

Rapsons used to do this on their Scottish Citylink coaches in the late ‘80s, no doubt to disguise the age of the vehicles.

The set back screen was to reduce glare. It was also used on Bet and weymann hermes bodied buses of the 1960s. Leyland was breifed by the NBC that their new design must feature all flat glass to reduce cost. A flat vertical slab of glass however is prone to sun glare.

Yes it sure is. The analogue computer opens a solenoid valve under the back seat of the bus. This dumps the air out of the air throttle ram for just over a second. It prevents 2 gears being engaged at the same time preventing damage

@@cptvhiltz I've heard so many fully auto Olympians with broken throttle dip valves making it sound like drivers are slamming the gears. It's a fragile system but a forerunner to the likes of the Volvo I Shift etc.

Hi Craig the bus does indeed have the later black CAV gear selector and LVA45 logicbox, just as you say same as the National and Olympian. Earlier buses has the black selector in the cab but still used the older CAV G2 logicbox. The LVA panel is a genuine Lothian one which features the non sequential downchange modification which makes it far smoother to drive over the standard CAV panel. Lothian didnt spec power steering on any of their Atlanteans. The drivers certianly had a bit more work to do over other companies buses.

5 speed pneumocyclic with LVA45 gearcontrol system.

So you keep the foot down? I've never seen a system quite like this. Seems to work well.

Fully automatic, the hiss is the sound of the system kicking in to allow a smooth gearchange

@@jamesfrench7299 It's essentially the same Pneumocyclic semi-automatic transmission as fitted to Atlanteans, Panthers, Leopards and most Nationals, but with a fully automatic control system added to automate the gear changing. You can hear the sneezing of the throttle dip valve which stops the gears slamming straight through. Earlier systems didn't have the dip valve and did slam straight through, presumably to the eventual demise of the gearbox.

@@scatmancraig1974 Hi Criag, the bus has an air thottle so the dip valve is located in the saloon under the back seat. In the video the seat is up, thats why you hear the sneeze clearly. Older Atlanteans had a cable or mechanical rods linkage for the throttle. On those buses the dip valve was on the engine right next to the fuel pump so you would never hear it over the engine noise. It was there doing it thing thou.

Hi Chris, I must do a new video. The bus is complete follow this link for photos. www.flickr.com/photos/calummelrose/48456405757/in/album-72157626226783921/

Funny, that's how sometime described the performance of one with TL11 and Voith combo. He said it's a rocket.

Yes a lot of drivers have some really silly ideas when it comes to how buses should be driven. A lot of what people have been told is third hand information or just simply applied in the wrong way. Common to all is how passionate people are about their point of view. Its rubbish you had to take the video down. Its correct you need to leave a gap between gear changes to allow for one band to release and the next one to take up. Visually you can see in this video just how long that pause needs to be. You will also see there is no revving of the engine required during up or down changing, its utter rubbish. It sounds good and gives the driver something to do when bored but it is not needed. A lot of operators and people go for semi auto conversion as its much cheaper than a repair of the ECU and the systems it needs to run. The control unit, brain, ecu, or whatever you want to call it is fragile and its not they get worse with age it just fails suddenly. Slipping gears is mainly due to brake band wear or glazing on pneumatic, hydracyclic can simply be an oil pressure set incorrectly or a leak. It is not difficult to get a gearbox running correctly if you have the information, tools, and skills. Sadly in preservation many don't so semi it is. My ECU failed through a poor earth, the unit had to be sent off for specialist repair, £200 just to open it and diagnose fault, add to that only one place I know of still fix them and replacement parts have to be salvaged from other LVA 45 panels I have spare as they ditched all their units.

Check out this video. This is fully automatic with a failed throttle dip so at risk of two gear lock up. Needless to say the bus was put away and repaired, and not driven like this for long th-cam.com/video/WfCgYEyYcA8/w-d-xo.html

@@cptvhiltz ah yes! I did give it a watch. So I'm assuming that it was at this point when the throttle dip started to fail on buses with the automatic system that all the issues would start with slippage between gears? I have seen a fair few automatic SCG/Leyland boxes were there was no throttle dip and usually there would be some amount of slippage usually it must be said between 2nd and 3rd which I'm guessing was due to those gears having the highest output of torque and higher usage

@@BusThrash buses ran with a failed dip all the time. This was a quick fix and it was back to its prime.

The Pneumocyclic gearbox is the same unit in both semi auto and fully automatic buses, all that changes is the method of control. There is absolutely no need for long pauses between gears the whole thing is a myth. You can is rubbish when you watch the LVA 45 system in action, its operating the gearbox as Leyland intended with a very brief delay of a second between gears. You have to laugh as its gotten so bad we now have some drivers who even rev a semi auto between gear changes as you would a 1920s sliding mesh manual gearbox. Its comical how little engineering understanding some people have when they try and add validity to the silly things they do.

Lothian fitted a full stainless Steel system to the X reg batch of buses in the 1990s. This gave them a very unique sound. The system had been removed from the bus when we saved her but it has since been fully reinstated along with eminox stainless fuel tanks.

@@cptvhiltz It sounds much nicer than the exhausts Yorkshire Traction fitted to their Olympians.

Throttle dip doesn't work.

Yes it was noticed right away and the bus put away early. The throttle dip system was repaired, see the new videos

Please don't say they were TL 11 ones!

Hi Smiffy, I thought the same but its running well at the moment with no smoke. The engine air cleaner housing was falling apart and had been for sometime. After getting a new one from the US I took the old one off to find it clogged with dirt and earth. Just like a turbo fault the engine has been struggling for air causing all of this awful smoke. So far it seems to have been cured, its nor perfect but its good for now. good old L10

Calum Melrose good to hear, there are so few of these left, so every one is significant!
