Hystory: The motorised double decker bus NS-Type.

The first motorised double decker bus was the NS-Type which was introduced in 1923 and was the first to feature a full covered top deck.

It built by the A.E.C. (Associated Equipment Company) was considered luxurious at the time with upholstered seats rather than the wooden benches, and the closed in top deck enabled buses to compete on level terms with the trams that had become popular as a cheaper alternative, and with lots of new urban development, the freedom of the bus to adapt to new routes unlike the tram or train meant it grew in popularity very rapidly.

The NS-Type stayed in production until it was withdrawn in 1937.
