L.G.O.C. / LONDON TRANSPORT AEC RENOWN 'LTL' CLASS
This picture, kindly supplied by John Perthen, and photographed at Brighton by his wife Margaret, shows
LT1076 from the London Transport Museum after years of careful restoration, on its first public outing - the
Historic Commercial Vehicle Society London-Brighton Run on 1 May 2005.

The London General Omnibus (LGOC) first introduced 3-axle / 6-wheel vehicles in 1927 with the LS ('London Six')
double deckers. Produced by the Daimler / AEC combine, they were the first double deckers with pneumatic tyres.
There were two main potential advantages to the 6-wheel arrangement. Firstly there was a legal restriction at the
time on the permitted weight per axle, which meant that the increase to six wheels would allow a heavier, longer,
and therefore larger capacity vehicle to be used. Secondly the two rear axles could both be driven by the engine,
providing more traction.
In August 1929 the prototype (LT1) of a double-deck AEC Renown 6-wheeler was delivered, proving to be the precursor of
a large and successful batch of buses that eventually ran to over 1400 vehicles. There was a somewhat 'dated' air
about the vehicle, with its outside staircase, but such features were to be modernised as batch delivery got under
way and the designed evolved. Production vehicles started to arrive in 1930 and, slipped into the deliveries were
five batches of single deckers, also known by the designation 'LT', although their technical classification was 'LTL'.
The single decker AEC Renown Model 664 was 29 feet 1 inch in length, and with an 18 ft 7 inch wheel base, both
measurements being slightly longer than their double deck relatives. All seated 35. Since the petrol engine was the
same as installed in the double deckers, with the weight of the vehicle considerably less, the performance was quite
sprightly. This resulted in them being christened 'Scooters' by their drivers.
Three batches of single deck LT's were delivered for 'central area' work, in lots of 50, 85 and 64 respectively,
with all the buses painted red. In 1932 a pair of green vehicles were purchased for use on LGOC's country routes
(LT 1427 and 1428). This made a total of 201 buses and coaches, and the whole lot were transferred from the LGOC to
London Transport on its formation on 1st July 1933. Lastly, a single private hire coach (LT 1429) was transferred
directly from Hillmans to London Transport when its London operations were compulsorily acquired by LT in 1934.
With a typical design life of ten years for a bus at that time, none of the vehicles was expected to be running past the
mid-1940s, but the onset of war changed all that. Shortages of replacements resulted in buses all over the country being
required to soldier on well past their expected lives, and a large proportion of the single and double-deck LTs were
still running after the war. The ex-Hillmans private hire saloon had unfortunately succumbed to enemy action in 1940.
Over the next few years a process of body refurbishment took place, and 'Scooters' were converted from petrol engines
to oil. Some of the discarded petrol engines may have been used to extend the lives of other pre-war London buses
living on borrowed time. So, while the double deck LTs were being progressively retired (the last ones expiring at
Upton Park garage in January 1950), their single-deck counterparts were having life-extensions while waiting for
delivery of the RF class single deckers that were to replace them.
The last of the LT 'Scooters' could still be seen operating from Bromley, Hounslow and Sutton garages in the early
1950s, and were finally retired as replacement RF's came into service during 1952/53. None was formally preserved,
and it was generally considered that the type had disappeared without trace. One example of the double deck version
(LT 165) was earmarked for preservation after the war, and can now be seen as part of the London Transport Collection.
Many enthusiasts were surprised, therefore, when two 'Scooters' (both from the second batch to be delivered) suddenly
appeared on the market some years ago. Although in extremely poor repair, such rare finds could not be ignored by the
preservation fraternity and both have subsequently gone to the best possible homes. LT 1059 is
now on long-term restoration at the London Bus Museum, Brooklands,
while the other example (LT 1076) passed to the London Transport Collection, and emerged fully restored in 2005
(see photo above).
Seeing a living, breathing 'Scooter' is an absolute delight for many enthusiasts, and a dream come true of 'Jurassic
Park' proportions. The possibility of seeing TWO defies belief !
Many thanks to Ian Smith for two excellent images to illustrate this profile.
FLEET LIST
===============
LT 1001-1050 (Total 50)
Thanks to Ian Armstrong's fine website about London bus
routes, we can track this picture down fairly accurately. LT1026 was based at Sutton depot in Bushey Road ("A"). It
was working route 213 which ran (at that time) Kingston - New Malden - Cheam - Sutton - Belmont, although on this
occasion the bus was only going as far as Sutton. LT single deckers shared this route with T-class Regals working
out of Norbiton garage. At the rear of the bus is the Fountain Hotel, which was (and still is) in Malden Road, New
Malden, so we know exactly where the picture was taken. The allocation number "21" on the side shows that it was taken
on a weekday between May 1952 (when the allocation "21" came into use) and May 1953 when RFs took over the route. It
is reasonable to assume that this bus was not re-allocated elsewhere after that, so we are seeing it in its last few
months of service. Perhaps the photographer knew that, and that's why he was there. (Photo by kind permission of

Delivered: January - April 1931
Chassis: AEC Renown 664 (1LT1), 110 mm bore engine. Survivors in 1950 converted to 7.7 litre / 95 bhp diesel from
scrapped STL class buses.
Chassis numbers; 664003 to 664052.
Body: 29 feet 5 inches long, 35 seat bus bodies. Front entrance with central rear emergency door.
Notes: LT 1001 delivered Jan 1931, all the others in April 1931. All red. Most allocated to Muswell Hill, survived
to 1952.
LT 1001 (GH 8049) c/n 664003, LGOC b/n 10327. Delivered to Hendon, then to Muswell Hill for Route 111. Withdrawn
by 1952.
LT1101 (GO 7150) at Victoria Station. Allocated to Leyton depot, this bus is working route 10 which ran
from far-off Abridge via Chigwell, Leytonstone, Bow, and London Bridge to Victoria Station. RTs were running this
route by 1950, so it must be before that. It certainly appears to be in very good condition for a bus that was probably
to be retired in a couple of years' time. (Photo: London Trolleybus Preservation Society)
Ray Wilkinson emailed me in 2012 and said "Most interesting website. I don't remember the 'Scooters' although they
were running in the area I lived in (at Wanstead) in the 1940s and 50s. However, I do just remember the double-deck LTs,
primarily on route 10. My mother used to shop in George Lane, South Woodford and I remember seeing (and occasionally
riding on) the open-staircase LTs going to Abridge. That's why I found your photo of a single-deck LT on route 10 most
intriguing: it was only ever a double-deck route in my memory (and in all the other photos I've seen of the route)."
"Incidentally, the 10A, which went from Green Man, Leytonstone to Epping, couldn't get under the railway bridge at
Snaresbrook, so it went via the level crossing in Eagle Lane. When the Central Line was electrified, the road under the
bridge was lowered and the buses were re-routed under it, and the route number changed to 20."
"As for the LTLs, it wasn't until the middle 50s that I discovered route 236 that ran at the back of Leytonstone station
(I knew the other side well!). By that time the LTLs had been replaced by Mann-Egerton TDs from T and AR garages, and I
did ride on them a couple of times."
