1. 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

2. 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.

3. Mechanical • TRAM Power design bogie • 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

4. 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

5. 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

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

7. Testing • Mock up • 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.

8. 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

9. 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

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

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

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

13. Easy to move Each LRV needs only 3 trucks to move
