In its early years, route 18 linked central London and Wembley
along the Harrow Road. In 1934, the main 18 ran from London
Bridge to Harrow Weald, via Euston, Paddington, Harlesden, Wembley
and Sudbury. Variants also served Park Royal, Brent and
Hanwell (the 18C, later renumbered as the 92).
With the need to
save diesel, the main service (18 and 18A) was replaced
at the beginning of the war by new trolleybus route 662
(electricity was generated from home-grown coal, so electric
traction was preferred). The main 18 was diverted at
Wealdstone and served Edgware instead of Harrow Weald; its southern
weekday terminus became Wembley Empire Pool.
Through Sunday operation continued, however.
On the opening of LT's Aldenham Works
after the war, route 18 was extended there at peak times, to
augment the Works' only other bus service, the 141 (later
morphing into the lengthy 107).
'Other' route 141 served
Aldenham LT Works en route from Edgware to Borehamwood up until
1954, when route 107 was extended to cover this section.

By 1950, the 18 was worked by STLs from Willesden (AC) and
utility Guys, later STLs, from Alperton (ON). The RT
family took over in 1950, with RTs from AC and RTLs from ON; with
the approval of central London RTW working, in 1954 AC's RTs
were replaced on Sundays by RTWs and ON's RTLs by RTs.
Operation from Middle Row (X) was added in 1958, using RTWs and
then RTLs.
The
transformation of the route back to a trunk route occured with the
penultimate stage of the trolleybus converion in January 1962, when
the 662 was replaced in turn by the 18. Stonebridge Park then
joined the operation, meaning the route was shared by 4 garages
over the week, with a peak requirement of 55 buses. SE and X
now provided Routemasters, brand new buses in the RM10xx
series. ON's allocation converted to RM in 1964, but AC
retained RTLs and RTWs until losing its Saturday share of the route
in 1968.
Arriving after a short
working, Middle Row's brand new RM1030 turns at Sudbury
Swan under under the trolleybus wires, soon to be but
a memory. But the roundabout is still used to turn by the
bendy buses. And this bus, in its final guise as RM1033, will
be in service on the 18 on 29 August.

On trolleybus replacement, the 18 also absorbed the remining
variant, the 18B, whose Brent section was withdrawn in
1958 (although the 18A, Paddington Green to Acton,
was reintroduced in 1967). The route now ran daily from
London Bridge to Edgware, with the peak hour extension to Aldenham,
although the Paddington to London Bridge section was unsurprisingly
withdrawn on Sundays in 1967.
In 1970, in keeping the developing trend to shorten routes, the
outer section beyond Sudbury was replaced by OMO MB-operated route
182, but the 18 retained its Routemasters, mainly RMLs from SE from
1975, until 1979. This was not an OMO conversion, however,
with crew DMs and Metrobuses being operated until 1986.
Over the next 10 years, the London end was gradually cut back
from London Bridge to Farringdon Street, Kings Cross and finally
Euston, from where todays First bendy buses still operate to
Sudbury.
