City Class 29.2400.3 Tram Presentation by TRAM Power Ltd. Unit 4 Carraway Road, Liverpool L11 OEE tel. +44 (0)151 548 7040 web : www.trampower.co.uk Prepared by Professor Lewis Lesley

Design Principles Proven design concept The City Class tram from TRAM Power Ltd. Has world wide application. Innovative design and “components off the shelf”. Components off the shelf (COTS) reduces costs Low initial, low maintenance and low whole life costs. The City Class tram is a highly efficient public transport vehicle. Can compete with buses on operating costs. Matches light rail for speed and comfort.

Mechanical TRAM Power design bogie All wheels separately rotate - low track forces (bogie weight = 2200 kg) All wheels separately rotate - eliminating curve squeal Wheels individually removable for maximum life (>300,000 km) Ultra comfort resilient wheel, need not be same diameter Smoother ride for passengers Central Articulation carried on two wheels best use of space

Electrical Body mounted traction motors - easy maintenance No equipment inside passenger saloon - full width flat floor The light weight (22 tonnes) reduces power saves more in electricity than the initial purchase price. saves on infrastructure requirements. Three phase AC drive, with regeneration to stand still Programmable acceleration / braking and jerk rates 10% gradient capable PLC “fly by wire” control system

Body & Structure Integral high strength body fabricated from rustless steel (long life > 30 years) Timoshenko crash worthy cab, with driver survival zone High passenger capacity (e.g. 200 in 29 metre vehicle) Compatible with all passenger facilities, e.g. air conditioning Easy mid life modification, adding longer articulation unit to increase capacity to 300 passengers Low floor (300 mm) and high floor (760 mm) options Length in 1500 mm modules, from 16000 mm to 38000 mm Width from 2400 mm to 3500 mm Height from 2900 mm (including double deck option) Flat articulation floor, with clear passage 1000 mm wide

Development Computer simulations laboratory models bench testing mock up slave vehicle prototype tram production vehicle

Testing Mock up Slave vehicle Prototype built 1993 for trade exhibition Slave vehicle 1930 tram with TRAM Power equipment at one end operated 1995 - 1997 Prototype tested at Blackpool 1998 and 2000 with HMRI approval.

Mock up 4 tonne Low/High floor - 25% length full size Exhibited and market research in Birmingham, Blackpool, Chatham, Dublin, Edinburgh, Gloucester, Liverpool, London & Sheffield

Slave Tram Redundant 1930’s tram for scrapping One original bogie and drive removed TRAM Power bogie 90kW 3phase industrial motor and Inverter drive fitted Tested on Blackpool Tramway 1995 - 1997

Prototype Tram 29m long single articulation bogie, motor and inverter from Slave tram with second identical set added tested with HMRI approval 1998 - 2000

Production Vehicle Prototype completely refurbished 2005 new motors smaller more powerful new inverters

The City Class Family 15 m horizontal track radius 100 m vertical curve capable Magnetic track brakes for emergency braking MU compatible

Easy to move Each LRV needs only 3 trucks to move
