The Scania N113 was designed as a successor to the N112. Most of the single-decker buses and the double-decker buses have a double-curvature windscreen with an arched top. It had an 11-litre engine mounted at the rear, coupled to either a Scania or Voith gearbox. It was available as:
London Transport was to be the biggest UK customer for the double-deckers, taking 71 between 1989 and 1992 for its London Northern and East London subsidiaries. Of these, 29 were bodied by Alexander,[2] the other 42 by Northern Counties. Brighton & Hove bought 51 between 1989 and 1998, all with East Lancs bodies. Yorkshire Rider took 42 in 1990 and 1991 (37 with Alexander bodies and five with Northern Counties bodies),[3] while West Midlands Travel took 40 with Alexander bodies in 1990.[4]
Busways was the first United Kingdom customer for the standard-floor single-decker in 1989, eventually taking 36, all with Alexander PS bodies.[11] The biggest customer, however, was Yorkshire Rider, which bought 55 with Alexander Strider bodies in 1993 and 1994. Newport took 30 Strider-bodied versions between 1993 and 1997, while GRT Group took 26 with Wright Endurance bodies in 1994/95 for its Midland Bluebird and Lowland Scottish fleets. Cardiff Bus bought 14 with Plaxton Verde bodies in 1992 and a further seven with Strider bodies in 1994, while Nottingham took eight PS-bodied versions in 1990. Among other customers were Yorkshire Traction, Tayside Buses and Stevensons of Uttoxeter.
In 1993, Kowloon Motor Bus purchased two Alexander RH-bodied Scania N113 tri-axle double-deckers. The Alexander RH buses all have a double-curvature windscreen with an arched top. They were equipped with Scania DS11-74 engines (274 bhp) and Voith DIWA863 gearboxes.[14]
Another 20 were purchased in 1996, but equipped with Scania's DSC11-24 engine instead of DS11-74. All were withdrawn between 2010 and 2014.
Singapore Bus Service took delivery of 200 Alexander PS bodied Scania N113CRB single deckers in 1989/90, 50 of which were air-conditioned and the remaining 150 non air-conditioned. Several of the non air-conditioned buses were retrofitted with air conditioning in 1998/99.
These buses served mainly the eastern parts of Singapore and were predominantly under the control of the Bedok North depot, with a minority at Ang Mo Kio, Braddell and Hougang depots. They were transferred to SBS Transit on 1 November 2001 and retired from 19 August 2008 to 1 May 2009. These buses were repainted between January 2004 and December 2007. Some of them were already replaced by Volvo B10M who in turn replaced by Scania K230UB. The N113CRBs operated on a majority of trunk, feeder and Townlink services in the East.
In 1997, Scania introduced its 4-series range of buses, which utilised smaller and cleaner engines in order to comply with Euro2 emission limits. The N113 thus gave way to the low-floor, 9-litre-engined N94. However, N113 double-deckers continued to be sold in the UK until 2000, the last examples being a batch with East Lancs Cityzen bodies built for stock and sold to a variety of small operators. The N94 was eventually introduced to the UK in 2002, in both single-deck and double-deck forms.
