The CR4000 is a 76% low floor model of Flexity Swift tram built by Bombardier Transportation in Bautzen and Vienna between 1998 and 2000 and operated by London Tramlink.

The CR4000[edit]

The trams are six-axle single-articulated double-ended cars, with four doors on each side. The low floor section stretches between both the outer doors through the articulation (which rests on an unpowered bogie). Each tram has an integral traction braking controller with deadman's handle. While stationary, the tram is immobilised until the driver's hand is on the controller: if the driver's hand is removed from the controller while moving, an alarm sounds immediately and the driver's hand must return to the controller to disarm it. If a three-second countdown passes and it is not disarmed, the track brakes are applied. Between the outer door and each car end is a higher-floor section, accessed up a step and situated over the car's two power bogies. The low-floor section is 40 cm (16 in) above rail-level, sloping down to 35 cm (14 in) in the doorways, a height that matches the platforms at tram stops, and each car has two wheelchair positions. The trams are 30.1 m (99 ft) long and 2.65 m (8 ft 8 in) wide, with 70 seats and a total capacity of just over 200 passengers. They operate from an overhead power supply at 750 V DC, and have a maximum speed of 80 km/h (50 mph). They are based on the very similar class K-4000 built for use on Cologne's low-platform routes. The fleet is maintained at Therapia Lane depot.

The trams are numbered beginning at 2530, continuing from the highest-numbered tram, number 2529 on London's former tram network, which closed in 1952.

Trams were originally fitted with destination blinds, which showed the route number, ultimate destination and intermediate points. These were replaced during 2006 with electronic destination indicators which show only the final destination of the tram. 2535 was named Stephen Parascandolo 1980-2007 at a special ceremony at Beckenham Junction on Saturday 21 October 2007. It is named after the webmaster of the Unofficial Croydon Tramlink website who died at the age 26 following a road accident. All trams have now been refurbished, including a repaint into a new lime green, blue and white livery.[1]

Future[edit]

As of July 2009, the Tramlink fleet is 24 strong, with four more trams planned. To avoid the extra costs of a short production run, Tramlink is seeking to lease these from Edinburgh Trams, where the construction of new track and depot is facing long delays, but the rolling stock is due for delivery from early in 2010.[2] The Edinburgh Tram vehicles will be manufactured by CAF of Spain.[3] To accommodate the extra capacity, some sections of single-track line may be doubled.[4]

In January 2011 tendering began for the supply of an additional 10 new or second-hand trams to be supplied to Tramlink from the end of summer 2011.[5]
