Renault PN

The Renault PN was a bus produced from 1926 until 1930 by the French manufacturer Renault for the Paris service, with a variant for suburban transport called the Renault PY. In 1926 the Société des transports en commun de la région parisienne (STCRP), the predecessor of the RATP, made its first major order of buses to Renault, for 50 new low-floor models with rear entry, and 330 PNs were delivered between 1927 and 1930 and stayed in service until the 1950s. Both the PN and the 1929 PY used a 5.03-litre flathead inline-four engine producing between 30 and 45 metric horsepower, a four-speed manual gearbox and double rear wheels, and the PN carried 39 passengers with a forward-control layout that put the driver over the engine and a low-entry platform at the rear. It was 8,190 millimetres long, and early models used solid rubber tyres that were later replaced by pneumatics.
