# Diamond North West

Diamond Bus (North West) Ltd., trading as Diamond North West, is a bus operator providing services in the districts of Bolton and Wigan in Greater Manchester, England, operating an extensive commercial network as well as franchised Bee Network bus services on contract to Transport for Greater Manchester. It also serves some areas of the districts of Salford and Trafford.
The company was founded as Green Triangle Buses and then subsequently renamed South Lancs Travel before being purchased by Rotala and rebranded as Diamond North West in 2015. In August 2019, Diamond North West purchased First Manchester's Bolton garage, which was later transferred with its vehicles to Go North West under Tranche 1 of the Bee Network.

## History
### South Lancs Travel

Green Triangle Buses was established in April 1998 by Martin Bott and David Stewart. The new business began with two new Mercedes-Benz Varios which were used on a Greater Manchester Passenger Transport Executive tender. These were joined by three South Lancashire Transport (also owned by the two partners) single deckers for use on school services.
Further Varios were quickly added to the fleet, which were used on Green Triangle's first commercial service, route 675 a half-hourly service between Leigh and Shakerley via Astley and Tyldesley.
Less than a year later, route 675 was withdrawn and replaced with the 670/680 circular services. This essentially provided an extension to the existing service, running back to Leigh via Atherton. This was supplemented through the introduction of route 652 (Leigh - Hindley - Wigan). All three services directly competed against the incumbent operator, Bellairs & Dootson.
An opportunity for expansion came in 1998 with the opening of the Trafford Centre. Green Triangle introduced two new daytime services to the centre in the form of the 673 from Atherton and the 674 from Leigh. The 673 only lasted a short time, although the link was later reinstated as the 132 and today continues to Wigan. The 674 continues to this day, although it is now numbered 126.
In 1999 the business of Bellairs & Dootson was purchased. The combined operation was rebranded as South Lancs Travel. In 2000 the depot was relocated to its current premises.
Since then, the company has steadily expanded its network, primarily through tender gains. This expansion took the company deeper into both Wigan and Bolton, with the most significant gain being the award of the GMPTE Easylink network of services.
Commercial work was also added, with SLT taking over route 592 (between Shakerley and Bolton) in 2002, acquiring the service from the one-man Atherton Bus Company following the retirement of the owner. This was linked up with an existing service to form a through service from Leigh to Bolton.
The company also added a network of services in western Wigan in 2005, when it purchased Blue Bus of Bolton's Appley Bridge outstation. This included a small network of services to Shevington, Standish, Orrell and New Springs. The Appley Bridge outstation closed in May 2007.
In 2006, entrepreneur Julian Peddle bought a 30% stake in the company.
South Lancs Travel have also been involved in head-to-head competition with First Manchester on a number of occasions. The most notable of these took place in 2002, when, following competitive registrations by First, SLT offered "return tickets for the price of a single fare" - First responded with a £2.00 (later £2.50 then £3.00) weekly ticket for travel within the Leigh area.
First also introduced a short-lived competing 652 service, albeit operating from Hindley Green to Shakerley via Leigh. More recently, First introduced a competing 635 service - SLT retaliated by introducing journeys on the 600 between Wigan and Ashton-in-Makerfield, and offering a £1.00 flat fare. Following the withdrawal of First Greater Manchester services to Shevington, the SLT 600 was withdrawn in May 2008 and SLT is now the sole operator of services to Shevington and Appley Bridge.
On 30 September 2011, South Lancs Travel was sold to Julian Peddle and Crewe based D&G Bus. In January 2012, Strawberry merged with South Lancs Travel and moved its operations to SLT's depot in Atherton. Strawberry's founder Oliver Howarth became joint operations director of the enlarged company. However, he left soon after with Strawberry being acquired by D&G and Julian Peddle and merged into the main company and the name and livery being dropped in favour of the SLT brand.

### Rotala ownership

On 1 March 2015, South Lancs Travel was sold to Rotala and rebranded Diamond Bus North West.
On 1 September 2017, Rotala purchased the bus operations of Go Goodwins, resulting in the acquisition of 18 buses and the Eccles garage on Old Wellington Road, Eccles.
On 11 August 2019, First Greater Manchester's Bolton garage was taken over with 18 routes and 125 buses. Following the commencing of Tranche 1 of the Bee Network from 24 September 2023, the garage, with its vehicles and routes, was transferred to Go North West.

## Services

Diamond North West runs franchised Bee Network bus services on behalf of Transport for Greater Manchester from two depots, one in Bolton, which runs services across Bolton, Bury and Leigh, and Diamond's main depot in Eccles, which runs local services around Salford, Trafford, Stockport, Tameside and Oldham, including the 309, 310, 343 and the 'Saddleworth Rambler' route 356 acquired from Nexus Move and Stotts Tours, and also school bus services as part of Tranche 3 of the Bee Network.

## Fleet

As of December 2024, the Diamond North West fleet consisted of 103 buses. Most of these are branded for Bee Network services, with fleets of Alexander Dennis Enviro200 MMCs, Mellor Orion bodied Fiat Ducato and Mellor Strata bodied Mercedes Benz Sprinter Transfer minibuses additionally purchased new for these services by Transport for Greater Manchester.
Following the acquisition of First's Bolton garage, Diamond North West mainly standardised on the Wright StreetDeck double-decker bus, taking delivery of 128 StreetDecks throughout 2020 and 2021 and purchasing others second-hand, including 13 StreetDecks from a cancelled First Leeds order, to replace buses being leased from the FirstGroup. As of 2025, 101 of these StreetDecks, alongside the operations of Bolton garage, were transferred to Go North West to operate under the Bee Network from 24 September 2023. Some of these were also transferred to Wigan garage. 9 examples continue to operate with Diamond under the Bee Network and the remainder transferring to Rotala’s other subsidiaries including Diamond Bus (Birmingham) and Diamond Bus East Midlands.
