Stagecoach in Newcastle

Other Stagecoach services operating in the city belong to different subsidiaries including the X24 express service between Newcastle and Sunderland and X34 between Newcastle and Horsely Hill which are part of the Stagecoach in Sunderland brand; and the 685 Cross-Pennine route between Carlisle and Newcastle which is operated by Stagecoach Cumbria & North Lancashire.

In 2007, the first batch of Alexander Dennis Enviro 400 double-deckers were delivered to Newcastle – these being part of a £55 million group-wide order.[3] The vehicles operate predominantly on the city's high-frequency routes: 1, 12, 22, 38, 39/40, 62/63 and X87/X88.

A further delivery in July 2011 saw Walkergate depot take delivery of twenty-six Alexander Dennis Enviro 400H double-deckers, as part of the government's green bus scheme.[4] These buses initially served on routes 39 and 40 from their introduction, until turn of the new decade, when they were replaced by new Alexander Dennis Enviro 400 MMC double-deckers. The Enviro 400H now operate on other high-frequency routes in particular services 12 and 22.

In 2016, twenty-four Alexander Dennis Enviro 400 MMC double-decker buses were delivered for services 62 and 63 (operated by both Slatyford and Walkergate depots), with this delivery allowing for some of the Alexander Dennis Enviro 400 from the original 2007 order to leave the region. A further 23 were delivered for services 39 and 40 in January 2020 which include additional audio-visual next stop announcements with scrolling LED displays, free Wi-Fi and USB charging points.[5]

Eighteen Alexander Dennis Enviro 200 MMC single-decker buses were also delivered in 2016, these being for routes 30, 31 and 36 (operated by Slatyford depot).

In September 2018, Stagecoach in Newcastle introduced weekend night buses on the following routes: N1, N30, N39, N40 and N88.[6] These services were withdrawn in July 2019, owing to low usage.

In 2019, the company launched The Seasider open-top service, which takes in the sights of the North East's coast. The route serves North Shields, Cullercoats, Tynemouth and Whitley Bay.[7] The launch of the coastal service coincided with the end of the company's City Sightseeing franchising agreement, with the open top double-deckers being deployed onto this new route, in order to engage with a new customer base in North Tyneside.[8]

On Monday 28 March 2011, Alexander Dennis Enviro 400 (19151), NK07 HBL suffered severe fire damage after its engine burst into flames in the Killingworth area of Newcastle upon Tyne.[9]

On 31 December 2008, Alexander Dennis Enviro 400 (19380), NK58 AEU was de-roofed after it hit a Metro bridge 54.9885°N 1.5395°W / 54.9885; -1.5395 at The Avenue (around 400m west of Wallsend Metro Station). The accident happened after the driver had apparently took a wrong turn, leading to minor injuries and brief Metro speed restriction.[10] The vehicle returned to service six months later in June 2009.
