In this shot you can certainly see the difference in height between this highbridge KS and the height of the Lodekka both of which had the centre isle seating plan. The KS series succeeded the K series in 1950 when body length was increased from 26ft to 27ft, the extra foot was split equally between the bonnet length and the saloon. The reason for the extra 6in on the bonnet length was so the Gardner 6LW 8.4 litre diesel engine could be fitted without any modification being needed which was the case with the K series. Main production did not last very long as in 1953 the Lodekka went into production but I have read that the last KS was actually delivered in 1957. The “W” in the coding stood for wide meaning the body width was 8ft instead of 7ft 6in, there seems to be two schools of thought what the “S” stood for:
(a) “Short” as if Bristol knew that a longer chassis would be allowed a few years later and “L” would be used to differentiate.
(b) “Standard” being that the bonnet was of a standard length to allow installation of all engine variants.
There is also the belief that all of the KS series were bodied by ECW (Eastern Coach Works).


I had been under the impression, that the “S” stood for “stretched” to 27′ Source: “The Pocket Encyclopaedia of Buses & Trolleybuses since 1945”, London, Blandford Press, 1968 p.115

I was on a KSW at a rally today and overheard an apparently knowledgeable chap saying that the S indicated short, as opposed to KL which was going to be a 30-foot export model until Bristol’s government lords and masters prevented them from building for export at all.
However, the apparently knowledgeable chap thought we were on a KS, not a KSW, so the usual pinch of salt applies.

The Bristol KS was introduced following an increase in permitted length for double deckers from 26ft to 27ft in mid-1950. Later that year, the maximum permitted width for all buses was increased from 7ft-6ins to 8ft. and Bristol responded with the KSW. (The ‘S’ apparently stood for ‘Standard’ or ‘Short’ length chassis, with the ‘W’ predictably denoting ‘Wide’). At that time the bus industry had hoped for an increase in length to 30ft for all buses, but in the event this was limited to single deckers. Bristol had envisaged extending the K type to 30ft long (KL/KLW) but this did not materialise as a result. When legislation did allow for 30ft double deckers in 1956, the Lodekka was in its ascendancy and so no KL/KLWs were built.
ECW designed a 4-bay body for the KS-series and these could also be identified by the stepped panel below the windscreen. Although ECW bodied most of the KS-series chassis, Rotherham Corporation received six KS6Bs in 1950, fitted with East Lancashire bodies built in Bridlington. Rotherham was the only operator outside the Tilling Group to operate the KS as far as I am aware – these being ordered before the cut-off point following nationalisation of Bristol and ECW.
Bristol/ECW were not allowed to supply vehicles to concerns outside the British Transport Commission, following nationalisation by the Labour government in 1948. The ban was to appease the Conservative opposition and private sector manufacturers, and to prevent what they claimed would be unfair competition. (A clause was included to this effect in the 1947 Transport Act as a result). Restrictions on ECW’s output were also imposed, even within the BTC empire itself. Had this not been the case maybe ECW would have bodied some of London’s RTs.
The last KS (a KS6G) was delivered to Brighton, Hove and District in 1957, and the last KSW (a KSW6G) was delivered to Bristol Omnibus Company the same year.

Some 7ft 6in KS chassis received 8ft wide KSW bodies. Eastern Counties had quite a few, and a former ECOC driver reckoned in conversation that they needed to be driven rather gently when heavily laden, as they tended to lean alarmingly on bends.

Stephen Ford


Fascinating stuff indeed Brendan and I seem to recall that, nearer home, West Yorkshire had a few L and K type chassis with 8ft wide bodies.  In my view this is a very dubious practice especially with lowbridge double deckers which are prone to “nearside leaning” at the best of times.

Chris Youhill


I tend to agree with you Chris. Fitting bodies six inches wider than originally intended for the chassis does not sound unreasonable in theory. However, in practice as you say it would lead to increased body roll when cornering. You’re comment about “nearside leaning” with lowbridge buses was interesting, and something I’d not previously given much thought to. To the uninitiated it must have been quite entertaining going around a tight right-hander at times, and things would no doubt liven up even more as the leaf springs became tired with age!

Brendan Smith


The last ‘K’ type Chassis built was indeed delivered in 1957. It was actually a ‘KS6G’ supplied to the ‘Brighton Hove & District Omnibus Company’ fleet number 500 and registered ‘MPM 500’. The reason for the reversion to 7’6″ Bodies was for two way operation in the narrow St. James’s Street in the heart of Kemptown, Brighton. St. James’s Street is nowadays one-way (eastbound). BH & D was one of the last former Tilling companies to take the ‘Lodekka’ which it did so in 1959, taking eight ‘LDS6B’ the fore-runner of the ‘FS’ Chassis with the recently introduced Bristol BVW Engine.

1 National Travel, Manchester United Driver from Scarborough who had purchased/preserved a 1930’s (?) Bristol half cab which he wanted to be transported in at his funeral! Memory is a bit vague as to whether the bus was rebodied etc. but I think it was a JOG type Bristol. Anyone got any ideas?

This would be Charlie Bullock, Pete. See the link www.thescarboroughnews.co.uk/news/

The United driver that Pete Bradshaw is thinking of was Charlie Bullock who owned a 1940 K5G, FHN 923, which have been converted to a recovery truck. His final journey to Scarborough crematorium in August 2012 at the age of 97 was indeed made on that vehicle.
