technical characteristics
body completely welded in carbon steel. All sections are bent or pressed so as to obtain utmost rigidity and lowest weight.
interior of car modern and comfortable. Efficient insulation for heat and sound. Hinged exterior doors.
two engines OM-BXD, direct injection, 4 stroke, mounted with special flexible suspension on body. Main characteristics: continuous power output for each engine: 150 HP at 1500 r.p.m., cubic capacity 14,33 litres, cylinders: 6, vertical, in line; bore 130 mm; stroke: 180 mm.
hydraulic torque converters OM 1,15 Swenska Rotor Maskiner licence, three stages, fitted with double clutch so as to allow direct drive with the mechanical elastic transmission and exclusion of of the hydraulic system.
transmissions to the reverse system of the driving axles with telescopic shafts with cardan joints and with the interposition of two free wheels fitted into the hydraulic torque convertor.
two-axle bogies fitted with double leaf springs suspension between the swing beam and the bogie frame and with coil helical springs between this and the journal boxes equalisers. The axles are fitted with wheels having separate tyres of a diameter of 900 mm. The axle boxes are fitted with oscillating type roller bearings.
range at an average speed of 85 km.p.h. with a supply of about 450 Kg. of fuel oil: 750 Km
controls are the electro-pneumatic type with the possibility of controlling four engines from a single control desk. This allows trains to be formed of 2 railcars and 1 or 2 trailers.
electrical equipment is fed from two dynamos of 1400 Watts each, mounted of the engines and from two batteries giving 280 Amp/hours each. Internal lighting by fittings and bulbs. Signalling lights with arrangement for change of coloured glasses.
heating of the car by circulation of hot air obtained by two heater sets under the floor of the coach which utilise the heat from the engine cooling system.
drawgear and buffers. Coupling through rigid drawgear and buffing of light type. Adaptors to standard traction drawgear are available.
brakes are pneumatic and automatic, a high braking ratio assuring fast action. Geared down handbrake.
