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– 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
– 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– smaller– more powerful
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
