Weitzer railmotor
The petrol- electric railcar vehicle factory Weitzer János Rt from Arad with an internal combustion engine of the French manufacturer De Dion -Bouton was the first mass-produced combustion railcars in Europe.
History
The Hungarian Trade Minister Lajos Láng prompted in 1902 the development of an internal combustion engine car in order to reduce operating costs on branch lines.
First, two railcars were built with mechanical gears. A flask equipped with a Daimler- motor, the other with a Bánki engine. Both prototypes did not work as desired. The company Ganz & Cie. bypassed the problem in the conventional way by installing a De Dion -Bouton steam engine. Thus, the series Cmot VIIIa and VIIIb of the Hungarian State Railways Magyar Államvasutak ( MÁV ) emerged. The company took advantage of Weitzer contrast, another drive variant of De Dion -Bouton, the 1903 sea trials proved successful and ultimately in 1906 led to the scheduled use.
Technology
From De Dion -Bouton in 1900 a passenger car of the Belgian company Pieper was equipped with a gasoline- electric drive, using a single-cylinder four -stroke engine. Weitzer applied this principle in a somewhat larger scale, with a 50 or 70 hp De Dion -Bouton four-cylinder engine to power a generator, which fed two placed under the car floor electric motors of 30 hp. This in turn drove each to one of the two axles. The associated electrical equipment supplied to Siemens -Schuckert. Top speed was between 60 and 70 km / h The operating voltage was chosen so that current from the overhead line could be used on electrified lines.
The frontal compartment of this institution vehicles housed both the cab means and the motor-generator - generator set. By way of derogation from the prototype, the production car on the roof had an elongated pipe system for cooling. The cars were equipped at both ends with couplings, the standard gauge versions with additional buffers. They could carry up to two sidecar light construction.
Types and distribution
At least 41 standard gauge railcars went to Aradi és Csanádi Egyesült Vasutak ( ACsEV ). The car bodies of the prototypes resembled largely the same built steam railcars MÁV with a single entry platform at the rear end of the car. With a service weight of about 15 tons, they offered 40 seats. In series longer then cars were built. They had a central entrance and two classes of cars.
Two railcars purchased in 1907, the Romanian state railway Caile Ferate novels. The cars had the first and third class compartments and two vestibules, one end platform for the third and a central platform for the first class. These cars were on the roof in the longitudinal direction of the exhaust with a long silencer.
Four somewhat smaller cars with the same drive and similar layout as the ACsEV cars used the Alfoldi Első Gazdasági Vasút ( AEGV ) for intra- local lines of its 152 km long narrow gauge network with 760 mm gauge 1906/ 07 bought two directly at Weitzer, two in 1916 by the Gyulavidéki Vasút ( Gyulalandbahn ).
The meter gauge local railway Arad - Podgoria was opened in 1906 with eleven Weitzer De Dion -Bouton motor coaches. The name of the former railway company Arad - Hegyaljai Motorosított Vasút ( AHMV ) pointed to the motor drive. However, already in 1911, the company electrified its network, replacing the gasoline electric vehicles by EMUs. The Weitzer railcars were rebuilt in 1913 to non-powered coaches with luggage compartment.
The Nyíregyházavidéki Kisvasutak ( NyVKV, about Nyíregyháza - land narrow gauge railways ), who joined since 1905 Nyíregyháza with Dombrád and had a track width of 760 mm, acquired in 1906 and 1907 a further four Weitzer railcar. In 1911 they built the railway in Nyíregyháza for electrical tram out and bought by Ganz & Cie catenary railcars for city traffic, but also petrol electric railcars. The gasoline- electric railcars of overland route were equipped with pantographs, so that the traffic within the city could be purely electrically conducted.
Whereabouts
After 1945, the remaining cars came into the possession of MÁV. Six of these cars, which were now referred to as BCmot 331 to BCmot 337 (excluding 335, " BCmot " stands for " railcar with the second and third car class ") came in 1960 at the suburban railway Budapesti Helyiérdekű Vasút ( bHEV ). The two underwent a fundamental overhaul of the car, replaced the petrol engines by diesel engines, generator and electric motors replaced and renewed the car bodies. The cooler on the car roof was henceforth hidden behind a modesty panel. One of the cars was worked up again shortly after the turn of the millennium. As a historical vehicle since he wears the number DM XII. Another of the six railcars is elsewhere in a museum.
