AEC Reliance
Alexander B45F

The Reliance in the snow above was being driven by myself on route 64 Newcastle under Lyme to Market Drayton on the A53 road just south of Loggerheads, traffic in front was getting stuck on a hill ahead of us called Hennel Brooke. The AEC’s were delivered in 1961 there was 25 of them all 45 seaters with Alexander bodywork built to BET federation specification, they were all withdrawn in 1976. They were the first OMO buses to operate with PMT, and yes we did eventually reach our destination.
They were a very pleasant bus to drive having a top speed of about 52 mph with a 5 speed gearbox powered by the AEC 470 engine. Bus number SN886 of this batch was "Tuned" to operate a service along the M6 motorway to Stafford from Newcastle under Lyme. It was not that much faster than the rest but it did have a good exhaust sound, just like the older Reliances with a crackling exhaust and a whistle when going downhill with your foot off the gas.

Newcastle was the first depot to have OMO single deckers and SN882 was one of the original conversions for the highly rural Newcastle Area services. It looks to have a smaller PMT logo on the front panel dating the photo post 1968 but has not yet had the destination display altered to a final destination with triple route number below. SN882 was one of a batch of 25 which were the first Alexander bodies for PMT leading to further orders for the second and third batch of Fleetlines followed by batches of Y type dual purpose bodies on both 8U2R (coil spring) and 6U2R (leaf spring) Reliance 691s. The Reliance 470s like SN882 had continual cylinder head gasket problems which led to instant cold heaters and demisters due to air locking and also had reliability issues with the hydraulically operated clutch mechanisms. The Alexander bodied 470s always seemed a bit flimsy to me compared with the earlier Weymann bodied examples.

1957
AEC Reliance 470
Weymann B44F

This is one of many AEC Reliance 470 with standard BET style Weymann bodies (B44F) operated by PMT. This particular example dates from 1957 denoted by the 7 prefix to the fleet number. Allocated to Milton Depot at the time, it has come to grief sliding into a ditch adjacent to some road works whilst on an inward journey on the 43 from the village of Stanley to Hanley – which is the main town of the Stoke on Trent conurbation. Milton Depot had an allocation of about 20 buses, mainly single decks for services such as the one shown plus three lowbridge Atlanteans and I think three MCW highbridge Leyland PD3/4 for the Hanley to Abbey Hulton services. Inside the depot was a survivor – engineless AEC Regal ex fleet number S315 KEH 608 which was in use as the staff canteen. It later went to Hollis of Queensferry for preservation – wonder what happened to it? Going back to SN7693, I remember a call we took concerning a bus on fire somewhere out in the Staffordshire countryside. It turned out to be SN7680 of the same batch but by the time we reached it in a narrow country lane all that remained was a chassis – and some burnt grass banks either side of the road.

These were the last batch of this type of body they had stick operated doors, Newcastle garage finished up with SN7688 which I would drive often as I thought it was a much better bus than the new Reliances we had with Alexander bodies, it had a good exhaust on it too.

Michael Crofts

Strange you should mention stick operated doors because Trent’s Tiger Cubs of the 1950’s had them. I remember thinking they had two gear sticks! The one to the right of the driver was forward when the doors were closed and then pulled back (a good pull was required!) and this pulled a flexible wire through a tube to open the doors, which were a mixture of jack-knife and two-piece. I often wondered if many fleets specified this apparatus. It fell out of favour by the end of the 50’s when something more sophisticated was felt necessary!

Chris Barker

Sheffield Transport amassed quite a fleet of Leyland Leopard Coaches between 1959 and 1961 with Weymann Fanfare, ECW and Burlingham bodywork. I did not have much cause to travel on them but I do remember that some, at least, (including the Weymann?) had this stick operation to their doors. These were full coaches with proper, heavy, coach doors – in the days when no coach had air assisted doors.

David Oldfield

My recollection is that earlier PMT Weymann bodied Reliances SN5573-5612 had electrically operated doors. I think lever operated doors commenced with SN6627-6646 and continued right through single deck deliveries including the 34 Albion Aberdonians until the ‘Jubilee’ batch SL801-810 when power operation recommenced. We avoided OMO conversions on lever door vehicles for as long as possible and of course the Aberdonians were never modified for OMO.
David mentions the lever operated doors on the Sheffield Leopards and I can recall a trip out to Bakewell on one of the B fleet Weymann Fanfare vehicles when fairly new (probably early 1960) where a friend and I sat on the front nearside seat and assisted with operating the door by hand as the driver was having difficulty with the lever operation from the cab!! The Fanfare vehicles were never modified to power operation whereas the Burlingham and ECW batches were later converted for OMO which included power operated doors.

Ian Wild

All the AEH reg batch AECs had the stick doors along with all the Albions.

Michael Crofts

With the delivery of 25 Alexander bodied Reliances in 1961, this brought a total to 150 of the 30 foot Reliances at PMT, most having Weymann bodies apart from another 10 Willowbrook bodied ones.

There were also a few Albion versions with this body operating Chell to Longton at this time. All three, Leyland, AEC and Albion had their own distinctive engine sound.
Anyone know who made the engines for the Albion?

Mr Anon

11/12/11 – 06:57

The Albions would have been Aberdonians – light-weight Leyland Tiger Cubs. The lightweight was in axle and chassis construction. They both shared the same Leyland Comet engine (0.350 version). Albions always had Albion gearboxes. [At different times, the Tiger Cub could have either a Leyland or an Albion box.]

David Oldfield

11/12/11 – 06:59

The Albion Aberdonian was a lighter weight version of the already lightweight Leyland Tiger Cub. It was powered by the Leyland O.350 engine of 5.76 litres giving 94 bhp, and was coupled to the Albion five speed constant mesh gearbox. It proved to be something of a frail beast, and most of the operators that tried it didn’t come back for more. Production ceased around 1960.

Roger Cox

The Albion Aberdonian had the same Leyland engine as the Leyland Tiger Cub, but strangely no Tiger Cub growl.

Peter Williamson

11/12/11 – 16:11

I always preferred the Aberdonian to the Tiger Cub, partly because I was brought with them. North Western’s batch of six spent most of their lives at Oldham depot and were the mainstay of the Saddleworth local services, running past my front door every half hour. I always thought they were quieter than the Tiger Cub and in retrospect I put that down to the Tiger Cub’s fan, although I don’t know if I’m correct in this.
The Albions had, shall we say, a distinctive vibration when idling. The only Aberdonian in preservation to my knowledge is the East Yorkshire one and that made the same sounds despite having a different body. It’s a bus I haven’t heard of for many years – does anyone know of its current status?
There are a few pictures of North Western’s Albions in my Saddleworth Buses gallery at: //davidbeilby.zenfolio.com/ where they will be found in the 156, 157 and 158 collections. (This gallery is still developing but the collections relevant to these buses have been done.)

I too had a soft spot for the Aberdonian, despite my only first-hand experience of them being the Manchester ones with Seddon bodies of almost third-world standard. I always feel that the model had a rough deal being marketed as an alternative to the Tiger Cub, as an urban bus or express coach, when it would have been much happier doing the sort of jobs that Bedfords did – pottering around villages on market days or providing day trips to the seaside – but giving the passengers a more refined experience than a Bedford could.
As far as I know, Plaxton-bodied Aberdonian coach XUP 692 is still with us, but it now very audibly boasts a Leyland 401 engine, and by all accounts goes like a rocket. I wish one of the Charlie’s Cars Harringtons had survived.

Peter Williamson

13/12/11 – 11:21

There’s an idea for another thread on the web-site – re-engining with similar, but different and larger, engines. I am already aware of AV760 powered RTs and RMs!

David Oldfield

When I drove for Stanley Gath of Dewsbury he had an ex O.K Motor Services Roe bodied AEC Reliance RUP 768 that had a rod operated entrance door. The bus was always called Rupert for obvious reasons.

Philip Carlton

I used to go to work on the Albions from Chell to Hanley and the gearbox seemed to be arranged from right to left, very different from the Leyland and AEC.
Can anyone verify this?

Clive Reynolds

27/04/14 – 08:06

Clive, the gear selector gate on the PMT Albions was exactly the same as any other bus in the fleet. They had a five speed Albion constant mesh unit fitted. The linkage was very sloppy giving the effect to the driver of stirring a very thick pudding when trying to locate each gear!
The Tiger Cubs that were acquired from Stratford Blue in 1971 had exactly the same gearbox but with a Leyland designed selector arrangement. The gear change on these was much more positive (and heavy!) but once you acquired the knack, I always thought a pleasant bus to drive. Mind you, I didn’t have to operate them in service on one man services.

With regards to the electric operated doors, SN5573 to SN5612 plus SN6627 to SN6646 were so fitted.

Daimler Roadliner SRC6
Marshall B50F

This is one of the prototype Daimler Roadliners which originally had the Clayton COMPAS heating and ventilation system fitted. There were two radiators, one each side of the bus just in front of the rear wheels which had the twin function of engine cooling and saloon heating. Sounds good in concept but like a lot of things at that time didn’t work reliably in practice. In January 1969 it reappeared with a front mounted radiator and conventional heating, the only PMT Roadliner so fitted. The radiator is hidden behind the front grille, which may look familiar to some as it was the grill fitted to the contemporary Ford Transit van. I cannot remember now why PMT fitted a front radiator to SN1000 and not a rear mounted one in the engine bay like the rest of the fleet. Incidentally the last 6 of the Marshall bodied Roadliners fleet numbers S1086-S1091 also had the COMPAS system – and they were no more reliable than SN1000!!
This was the only PMT Roadliner with air suspension, all the others had Metalastik toggle link suspension. The photo was taken on a test run near Clayton Schools on 20th January 1969.

I have driven these buses and they were a total disaster, PMT only kept them for about 7 years.

Michael Crofts

I remember the PMT Roadliners. Some of them had home made looking slits in the panels behind the back wheels to improve engine cooling. They were very noisy.

JT

Yes very noisy but sounding totally unlike a bus. It was a sort of deep "Ewwww" muffled roar. When North Western Fleetline 189 was fitted with the same Cummins V6 you could hear it descending Rassbottom St in Stalybridge (On the joint route 90 to Marple) long before it turned into the bus station.
I now regret that I never did take a ride on a Roadliner when I had the chance. A Potteries mate says they were just as deafening from the inside, and that the later Perkins engined ones whilst marginally more reliable, used to waggle their tails dramatically when driven at high revs.
Darlington and Chesterfield Corporations got long service lives out of theirs, whether that suggests they overcame many of the problems, or that the local councillors refused to give up on them for the costs and red faces involved in replacing them early?

Keith Jackson

When I was a boy the PMT Roadliners operated on route 13 to Bentilee. Apart from the noise the bodywork rattled fit to disintegrate! There was an emergency exit window half way along the off side the locking mechanism for which used to jiggle about when the bus was stationary. A big disappointment after the AEC Reliance 590s.

John Tinsley

Our problem at PMT was that we just had too many of the things!! The largest fleet of Roadliners anywhere in the world. The Plaxton bodied ones (timber framed bodies)could possibly have gone on to nearer normal service lives if re engined with Perkins V8s – but at what cost? The Marshall bodied ones (steel framed bodies)were disastrous and although we rebuilt a few at enormous cost in man hours they weren’t a right lot better. By 1972 failures of the Metalastik toggle link suspension units were becoming prevalent. These were expensive to buy and a nightmare to replace. Panhard rod bushes were a recurrent failure – again taking much longer to replace than a leaf spring on a conventional vehicle. We used saloon seats from withdrawn Marshall vehicles to replace the worn out high backed seats in some of Reliances SN801-810 making them more suitable for urban work and less susceptible to vandalism. Happy days!!

Ian Wild

Just a bit of clarification about the ‘home made looking slits’ (ref JT). They were fibreglass corner panels made in house in the fibreglass shop at Stoke and as JT says, the idea was to provide additional engine bay cooling. To the best of my recollection, they were fitted to the 47 Cummins engined Plaxton and Marshall bodied buses. I don’t think they were fitted to the later batch of 10 Plaxtons with Perkins V8 engines.

I worked with Cummins at that time and spent a year or so carrying out a series of engine changes and modifications for Belfast Corporation. As it was the time of the troubles, suspect much of my efforts ended up as bonfires.
V6 engine wet liners incredibly sensitive to both corrosion and erosion/electrolysis if water filters maintenance neglected. Becoming porous within months.
