For new connections: the Train-Tram
As leading supplier in the Valencian Autonomous Region, Vossloh Rail Vehicles has designed the first Train-tram in Spain, a new transport concept that is less contaminating, faster and more efficient.The train-tram is a light articulated vehicle that functions as a suburban train in the metropolitan area and as a tram in the urban context. This is a bidirectional electric train unit, capable of surface and underground travel. Travelling from outside a city to its interior without having to change is the great advantage of this mixed system, making it possible to achieve travel times that are very competitive by comparison with other means of transport.
With a design that is unique, coherent, functional and comfortable, current aesthetics and a very modern image, the train-tram is the solution from Vossloh Rail Vehicles for increasing sustainability and promoting the use of collective passenger transport.
Further characteristics are that the train-tram is also suitable for handling the bend radii and steep gradients that are usual in urban traffic, admitting minimum radii of 30 metres and maximum ramps of 6 per cent.
It travels at 100 km/hr as a suburban train, with a great acceleration capacity of 1.2 m/sec2 as a tram with high braking power and a maximum speed of 70 km/hr.
Each train-tram unit comprises three articulated cars incorporating four bogies. There is a motor bogie at each end of the unit and two bogies, one motor and one non-driving, under the middle car. Each motor bogie has two independent motors located in each of the truck’s two axles. There is a low deck in around 60 per cent of the end vehicles, 36 cm above the road surface and the vehicle interior is diaphanous, with broad intercommunication passageways between the cars, creating a single passenger space.
The vehicle has air-conditioning, pneumatic suspension, low deck access platform, a large number of seats, space reserved for persons with reduced mobility, reserved space and racks for bicycles, low noise and vibrations levels, high visibility, large window surfaces and streamlining in the lower sides and ceiling.
Propulsion
Each vehicle’s drive unit comprises six alternating current motors that are completely encapsulated, three-phase, asynchronous, self-ventilated, with four poles with continuous power range and continuous couple. Located on the roof of each unit is the Onix traction equipment that supplies the two motors included in the corresponding bogie motor.
The drive inverter control comprises the "Agate" units that are fitted with 32-bit microprocessors that control the inverters using the pulse width modulation signal, or PWM generated by the set point emitters.
This drive system is included in the high voltage unit that also serves to pick up the electricity supply from the overhead line and the auxiliary supply converters.
The electricity pick-up unit is located on the roof of the middle car and comprises the pantograph, the over-voltage safety device and two extra-rapid circuit breakers. The safety device that prevents electricity voltages above the highest value permitted under normal operating is static and requires no adjustment and maintenance.
