RT4421:
Introduction:

RT4421 represents how most RT’s looked in their service lifes, in the standard mid 1950’s onwards livery. The body itself was originally mounted on an STL chassis forming one of the ill fated SRT class. Following withdrawal from London the bus went into preservation at an early stage. She has been owned by Ensignbus since 2001 from where she has made numerous public appearances and became a regular performer as one of the ‘specials’ on Routemaster last days 2003-05.

History:
The RT is surely one of the best know types of London bus with a look that is timeless as well as being a design classic. RT’s have featured in films, such as ‘Summer Holiday’ or James Bonds ‘Live and Let Die’ all adding to the familiarity of the type.

The first RT took to the road in service weeks before the start of World War II and hence became the only true Pre War RT, however with the other 150 of this batch entering service throughout the next two years before hostilities ceased production this first 150 are universally all known as the Pre War batch.

Following the end of the war it had been decided that the RT would form the majority of London double deck fleet and so started one of the great fleet replacements as war weary types such as the LT and ST were replaced as fast as possible. By 1948 RT’s were entering service in a steady stream, there were however numerous delays and shortages caused by the lack of parts and skilled workers this close to the end of hostilities. Body production was quicker than chassis leading to some new RT bodies being mounted onto STL chassis, thus making the short lived SRT class, (of which our own RT4421 is one, formerly SRT 119). To also help production non standard body builders were used in addition to Park Royal and Weymann, Saunders and Cravens also built a few hundred examples see RT1431

By 1955 bus use had dramatically declined and LT had more buses than it was ever going to need, so the first non standard types, the Cravens, were withdrawn. Further withdrawals continued as the new RM class started to appear in the late 1950’s. However the RT was a survivor and following its hey day where nearly 7,000 were in service they took a long time to replace. The last one (RT624) ran on the East London route 62 in April 1979 bringing to an end 40 years of operation of this type, a record many thought would never be beaten. However its successor the RM has now achieved this, its true to say that when people are asked to draw or describe a London bus it is generally one of these two types people will think off, such is the iconic regard they achieved however with the RT having been built in such austere times and having operated through such harsh conditions its longevity is a credit to its type.
