AFFORDABLE URBAN AND RURAL TRANSPORT SOLUTIONS PROVEN IN SERVICE HOW A LIGHTWEIGHT APPROACH AND HYBRID DRIVELINE CHANGES EVERYTHING! Greatly enhanced fuel efficiency and lower emissions figures are the result of our new approach to rail technology for smaller branch lines and tramways. Compare the traction arrangements below: Capacity: 85 Passengers Capacity: 60 Passengers MANY OF BRITAIN’s existing branch lines — urban and rural — depend on railcars which are also designed for high speed mainline operation. An example is the Class 153 single-car ‘Sprinter’ diesel unit, previously used on the Stourbridge Town branch. These have 285hp, 14-litre engines suited to 75mph regional service, and were a wasted resource on a short branch line with stops close together and 20mph maximum speed. rather than the demands of a local service with frequent stops. The Stourbridge shuttle is now run by PPM Class 139s. These have much smaller engines — 60hp and 2.3 litres — but equivalent performance: a result of using a hybrid driveline. The Class 139s are able to use a much smaller engine, as a result of a ‘hybrid’ arrangement. An underfloor flywheel stores any surplus energy providing additional acceleration even up a steep gradient. Energy normally wasted as heat during braking is returned back to the spinning flywheel, ready for use when next required. Local residents appreciate the new railcars which, compared to the ’Sprinters’ are perceived as almost silent, and emitting no diesel fumes. Standard gauge People Movers can be powered by LPG, ’bio-gas’, diesel or — with an electric motor — charged at station stops. In all cases, this innovative power system gives the smooth power delivery, and quiet passenger experience, associated with electric trams.... ...but without their huge costs for electrification and infrastructure! Stourbridge Town Depot With the Class 139, maintenance and repair is carried out at a small depot on the branch, there is no need to venture out on to the main line. A Class 139 dedicated to a particular branch line need never leave its home. Conventional trains — larger, faster and better suited to longer and busier routes — can be freed up to undertake more demanding services elsewhere. ONE CAR ENGINE TRANSPORTS SIXTY PASSENGERS WHILE THE SAME ENGINE ON THE ROAD RARELY PROPELS MORE THAN TWO... IMPROVED SERVICES WITH CUTS TO CARBON EMISSIONS & FUEL COSTS IN THEIR FIRST intensive seven-day-a-week operation, Parry People Movers Class 139 railcars are providing the best ever service on the branch line at Stourbridge. As a result of a quick turnaround procedure and brisk acceleration, the Class 139s run six return services every hour—while heavy rail rolling stock could only provide around four. 1 hour While the passenger space on the new railcars limits numbers to 60 per trip, there is capacity to carry 720 passengers in a single direction each hour. The heavy rail Class 153 railcar which previously performed the service could only provide 680 one-way passenger trips in an hour, with a fully-loaded capacity of about 85 passengers on each trip. The improved energy performance of the new Class 139 railcars has made big inroads into the quantity of carbon dioxide released into the atmosphere. It is calculated that the heavy rail units, while performing the Stourbridge service, produced 809 kg of CO2 per day. The new Class 139s have brought this down to only 240 kg of CO2 per day, all this despite offering the public those extra two return services every hour. The cost of putting fuel into a vehicle has been rising. Public transport operators once treated fuel as a minor cost compared with wages and the lease of the vehicle — not any more. A single railway carriage or bus can consume £1000 worth of fuel in a week at current costs. The Class 139 railcar, with an engine only the size of a medium-sized family car incurs a fuel bill less than half the cost of other modes.
