Daimler Roadliner
Marshall B50F
I have listed this under Halifax Corporation has that is who the Roadliner was on loan to at the time the photo was taken. I went on this bus to Brighouse on the 49 route which was normally serviced by double deckers maybe the intention was to replace them with high capacity single deckers. Halifax didn’t buy any Roadliners or any similar single deckers so the route must of carried on being serviced by double deckers.
I have tried to research which operator the Roadliner finally ended up with but to no avail, if you know, let me know, leave a comment.
By 1975 this bus was with the Transport and Road Research Laboratory at Crowthorne Berks, and was used for “Guided Bus” experiments involving the bus being guided by a wire buried in the road.

It was the Daimler demonstrator, a deal was struck with Bob Crouch at Daimler to keep the bus in Halifax but it would be released back to Daimler when needed for demonstration purposes, it usually worked the 5/6 circulars and later had a green roof.
The Cummins VIM V6 engine was a poor unit and lead to the early demise of these buses.
In Halifax the poor roads lead to chassis body flexing and the long chassis severely restricted route availability, also with long routes such as 48/9 it meant too many unhappy passengers standing up.
Finally at this time – it had to have a Gardner 6LX – or it was out!

I believe this bus was sold in the late 70’s through the Gov auction sales at the OSDD at Ruddington, Nottm., I was a fitter at the time, my apprentice and I had a drive around the perimeter, it still had the mountings for the experimental equipment and only about 4 seats were installed.

We had a number of batches with V6/V8 engines, with Plaxton Coach Bodies for express services, FAST/GOOD HILL EATERS, but required one driver-one coach, to keep them on the road.
The engine sound going through a urban area at 02.00 hrs. was out of this world!!!! Went back to LEOPARDS, after the 4th batch, that or buy a 2nd towing unit. [mind you all top management had Daimler cars by then, buy 9 get a free car?????]

Here is another picture of the Roadliner under evaluation in Halifax, taken, if my memory serves me correctly, near King Cross. Personally, I doubt that GGH seriously considered this vehicle as a contender for the Halifax bus orders. Knowing his fascination with all things in the bus world, I suspect that he wanted to try it out through curiosity alone.

I well remember the Roadliner from my time with Eastbourne Corporation in the 1960’s. The demonstrator CVC 124C arrived in Churchdale Road depot one Sunday afternoon, I can’t remember when, it was not used in service only inspected and must have had an impression on Mr R R Davies the manager as one was ordered duly arriving in mid 1967 as No 86 (DHC 786E). I was the first driver to take it out on service as a additional bus on service 6, the seafront route, the first one man operated bus for the Corporation which I must say did not go down too well with the residents of the Meads section of the route. Two more similar vehicles arrived the following year as No’s 90/91 (EJK 890/91) all three having two door East Lancs bodies and fitted with the Metalastik suspension. As many others have commented they were very raucous both inside and out the suspension also I seem to remember chattered quite a lot but their performance was a revelation. I believe all three had to have new engines before they had covered 30,000 miles. I recall that when selecting 1st gear when stationary the N/S front corner dipped quite noticeably. My lasting memory of these buses is of stopping on the seafront to pick up passengers when the engine cut out for no obvious reason and would not restart I then noticed in the N/S mirror smoke coming from the engine bay upon investigation I found the main electrical control box and master switch had broken loose and was swinging on it’s cables with terminals shorting on the exhaust pipe after very carefully switching off the master switch I found the short circuit had burnt a hole in the exhaust pipe. Meanwhile orders had been placed for Leyland Panthers, I left the Corporation in 1969 and the Roadliners quite soon after, it has to be said the Panthers were only marginally better.

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!!

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.
