Initial Capoco proposal On 3 September 2007 the Conservative mayoral candidate for London,
Boris Johnson, announced that he was contemplating introducing a modern-day Routemaster. In December 2007, the UK automotive magazine
Autocar commissioned the bus designer Capoco, designer of the innovative
Optare Solo, to come up with detailed proposals for a new-generation Routemaster. Their design, dubbed the RMXL, was a
hybrid technology
low-floor bus with a lightweight aluminium space frame, with four more seats and twice the standing capacity of the old Routemaster, and operated solely by a driver. The design incorporated disabled access through a closing front door behind the front wheels while retaining open platform rear access, with the staircase still at the rear. The hybrid drivetrain had a front-mounted continuous-revving hydrogenised petrol engine; this charged front-mounted batteries, which powered the rear wheels through rear-mounted electric motors. This arrangement, through not requiring a mechanical transmission, allowed for a low floor and a step-free entrance into the lower deck from the rear platform. Hydrogen storage tanks would be located under the rear staircase. The design was covered by the national press but attracted criticism from Livingstone as being too costly to justify and still not safe, despite proposals to monitor the rear platform with cameras.
New Bus for London competition Johnson backed the
Autocar / Capoco design in principle and suggested that he would hold a formal design competition to develop a new Routemaster if he was elected London mayor in May 2008. After winning, on 4 July 2008 Johnson announced the New Bus for London competition. An initiative of
Transport for London, the competition invited anybody, both companies and members of the public, to submit ideas for consideration. The competition had two categories, an Imagine category for general ideas and concepts, and a Design category, for more detailed proposals. In both categories, entries could be either "whole bus" submissions, or proposals for parts of the bus. The Imagine category called for the submission of imaginative ideas for a red
double-decker bus with a rear open platform, and one other entrance/exit with doors. The Design category called for detailed designs of a
low-floor, red double-decker bus with at least one internal staircase, a rear open platform, and one other entrance/exit with doors, to be crewed by a driver and conductor, and suitable for carrying 72 passengers seated and standing. The designs were required to satisfy a table of mandatory and suggested design specifications, and "be practical and economic and capable of being put into mass production". The competition offered cash prizes for entrants, with £25,000 for the winner, and smaller awards for good ideas. One initial set of proposals gained media attention after being unveiled during October 2008, for a "smiley bus" known as the H4 (designed by the H4 Group).
Future Systems offered a "space age" alternative powered by hydrogen.
Foster and Partners submitted a glass-roofed design. The winners were announced on 19 December 2008. There were 225 entries in the Design category, and 475 entries in the Imagine category The £25,000 prize for winning the whole bus Design category was shared between two entries, one from Capoco Design, a bus, coach and truck design firm, and one from a joint submission made by architects Foster + Partners and automotive company
Aston Martin.
Tendering process & final design The winning and other merited entrants in both the Imagine and Design categories for both 'whole bus' submission and part submissions were passed by TfL to
bus manufacturers, for them to draw up detailed final designs meeting all relevant legislation, and later presented to TfL for consideration on a competitive-tender basis. By April 2009, a formal invitation to express interest in the project was published in the
Official Journal of the European Union. In May 2009, six manufacturers were invited to negotiate the contract to design and build the new bus. They were
Alexander Dennis,
EvoBus (which includes
Mercedes-Benz),
Hispano Carrocera,
Optare,
Scania and
Wrightbus, having all met TfL's criteria for pre-qualification for tendering, which included demonstrating they had a manufacturing capacity of building 600 buses over three years.
Volvo Buses declined to enter the bidding process. Transport for London set a deadline of 14 August for the submission of detailed tenders; Scania and Evobus pulled out before this deadline. Scania did not believe they could produce the first prototype in the time stipulated, and Evobus had concerns as they were not at the time manufacturing any double-decker. On 23 December 2009, Northern Ireland-based vehicle manufacturer
Wrightbus was awarded the contract to build the Future Routemaster. The contract called for a bus with a capacity for at least 87 passengers, two staircases, three doors, and a rear platform which could be left open, or closed with a door when there was no conductor on board. Transport for London and Wrightbus worked with
Heatherwick Studio to produce the styling for Wrightbus' final design. TfL has applied to the Intellectual Property Office for Registered Design Protection for the exterior design. The body has two diagonal glass windows from top to bottom decks, one curving around the rear, the other on the right-hand side towards the front, which provides natural light to the interiors of both staircases. The rear staircase is in the same position as in the original Routemaster, curving around the rear section, while the front staircase is straight, ascending on the right-hand side of the chassis over the driver's cab, opening out in the front of the upper deck. The bus is certified to EC Whole Vehicle Type Approval and ECE Regulation 107, according to the manufacturers. The use of three doors and two staircases is not new to London: London Transport evaluated a prototype bus in the 1980s as part of the Alternative Vehicle Evaluation programme: a specially modified
Volvo Ailsa B55 with two staircases. These trials were curtailed due to the running-down and eventual closure of London Transport's bus Engineering Research department. == Production ==
