The LGOC NS-type is a model of double-decker bus that was introduced in London in 1923. It was designed by AEC in cooperation with, and operated by, the London General Omnibus Company (LGOC).{{cite book |title=The London Transport Collection |date=1973 |publisher=London Transport |location=London |page=5}}
Design
The designation NS was derived from "Nulli Secundus" – "Second to None.{{cite book |editor1-last=Taylor |editor1-first=Sheila |title=The Moving Metropolis |date=2001 |publisher=Lawrence King Publishing |location=London |isbn=1-85669-326-0 |page=209 |edition=2002}} The bus was fitted with a cranked chassis, allowing a covered top, lower floor and a single step entrance. The prototype was fitted with a temporary covered top but the Metropolitan Police wouldn't issue it with a licence so the bus entered service on 10 May 1923 as an open-top vehicle with solid tyres. In 1925, the authorities relented and covered tops were allowed. In 1928, pneumatic tyres were substituted for solid tyres and in 1930, the driver gained an enclosed cab..
Service life
Preservation
Only two examples have survived: NS 174 which is still in original condition with open top and cab, and solid tyres. It is preserved at the London Bus Museum.{{cite book |last1=Bowker |first1=David |title=Our Buses |date=2021 |publisher=London Bus Preservation Trust |location=Weybridge |page=9}}
The other survivor, NS 1995, is in its final configuration and is part of the London Transport collection.
