Definitions

  • the object of the invention is a system and a method for pushing or retaining a train on the steep slopes of a railway line by using a haulage cable and a push/retain assist vehicle. It is a known fact that the adhesion forces of locomotives prevent train compositions from overcoming steep slopes. This is why railways have long lines that make it possible to overcome substantial differences in altitude. Slopes, i.e. inclinations, on conventional railway lines reach up to 25 ⁇ , most commonly up to 17 %o. Today, rack railways are used for slopes up to 140 %o for passenger railway connections, while freight traffic does not go beyond 79 ⁇ . It is understandable that steeper slopes require a more powerful pulling force and this is normally achieved by including two locomotives.
  • the wagons with or without locomotive is coupled to the assist vehicle by specially designed holding devices (22, 23) and after pulling the train and overcoming the steep slope, the train is decoupled from the assist vehicle.
  • the system is using a pulling system with one axis which is not suitable for train compositions of huge masses since the weight of the assist vehicle should be equal to the weight of the locomotive.
  • the task of the invention is a system for pushing or retaining a train that will allow a simple, rapid and reliable driving of a heavy train on a railway line with a steep slope, where differences in height of 300 to 500 m are to be overcome and the length of the railway line will not have to be extended in a spiral loop or by other shapes of curvature.
  • the task is solved by a system according to claim 1.
  • the system allows a continuous drive of a train and the related drive of an assist vehicle by coupling the assist vehicle at the rear side, whereby in the upper section the assist vehicle is automatically disconnected and the train composition drives on without stopping or braking the train composition.
  • a mechanical and electronic system 6 supervises and controls the ascending and descending of the train composition 5.
  • the push/retain assist vehicle 3 is fastened to the steel cable 4 in the upper position and starts accelerating in front of the train composition 5 while descending in a way that the locomotive of the descending train composition 5 reduces the speed and that the essential part of the necessary braking energy is taken over by the push/retain assist vehicle 3 which then takes over all the braking energy during descending and translates it to the force of the steel cables 4 which are connected through huge drive wheels with the engine-generator of the system 6 in such a way as to allow conversion of the mechanical energy to electrical energy.
  • the push/retain assist vehicle 3 in the lower section then moves away from the locomotive of the train composition 5 by increasing the speed in order to reach the railway switch 1 considerably earlier and to move away from the line of the railway tracks, thus making it possible for the special railway switch 1, after the push/retain assist vehicle 3 has passed it, to assume a position, i.e. to switch the railway switch 1 into a position in which the train composition 5 can drive through the railway switch to a normal railway line and to ensure free access for a new train composition for hill climbing.
  • the system of the invention consists of a low-slope railway line with a train composition 5 and of a short railway line parallel thereto with a push/retain assist vehicle 3, both lines being connected by a railway switch 1.
  • the joined line starts from the railway switch 1 along the length of the train composition 5 with a low slope and then passes to a steep slope.
  • the route line of the push/retain assist vehicle 3 is a straight line 2 without any turns throughout the entire length.
  • the push/retain assist vehicle 3 is fastened to the pull cable 4 between the rails of the railway line 2.
  • the railway line passes from a steep slope to the line of a low slope; an engine-generator of the system 6 is arranged at this transition and has a bullwheel for the pulling cable 4.
  • the system for pushing or retaining a train consists of known devices and elements that are used in railroad traffic. By using all the accompanying devices and elements, the system provides for an uninterrupted drive of a train composition from takeover at the entry point at the lower section to discharge the train formation to a conventional railway network at the upper section.

Claims (3)

  1. System zum Schieben oder Halten eines Zuges auf steilen Gefällen einer Eisenbahnstrecke, wobei das System ein Zugseil und ein Hilfsfahrzeug umfasst, dadurch gekennzeichnet, dass das System aus einer Schienenstrecke mit niedrigem Gefälle, d. h. mit einer Neigung bis zu 25‰, für eine Zuggarnitur (5) und aus einer Eisenbahnstrecke für ein Schub-/Halte-Hilfsfahrzeug (3) besteht, wobei die Eisenbahnstrecke parallel zur Schienenstrecke mit dem niedrigen Gefälle verläuft, wobei die beiden Schienenstrecken über eine Weiche (1) verbunden sind und eine gerade verbundene Bahnschiene bilden; die verbundene Bahnschiene beginnt an der Weiche (1) mit dem geringen Gefälle und geht dann in ein steiles Gefälle über, d. h. mit einer Neigung, die die bei herkömmlichen Eisenbahnstrecken bekannten Gefälle um mehr als das Dreifache übersteigt, an ihrem oberen Abschnitt geht die verbundene Eisenbahnstrecke an einem Übergang von steilen Gefälle in eine verbundene Eisenbahnstrecke mit geringem Gefälle über, wobei der Weg des Schub-/Halte-Hilfsfahrzeugs (3) über seine gesamte Länge eine gerade Bahnstrecke (2) ist; das Zug-/Halte-Hilfsfahrzeug (3) ist an einem Zugseil (4) befestigt; das System umfasst weiterhin einen Motorgenerator (6), der am Übergang angeordnet ist und eine Seilbremse für das Zugseil (4) aufweist, sowie Reglern.
  2. Verfahren für das System nach Anspruch 1 zum Schieben oder Halten eines Zuges auf steilen Gefällen einer Eisenbahnstrecke unter Verwendung eines Zugseils und eines Hilfsfahrzeugs, dadurch gekennzeichnet, dass, nachdem die Zuggarnitur (5) mit ihrem letzten Waggon beim Bergauffahren die Weiche (1) vollständig passiert hat und die gerade verbundene Eisenbahnstrecke erreicht hat, ein Schub-/Halte-Hilfsfahrzeug (3), das sich mit einer Geschwindigkeit, die der Geschwindigkeit der Zuggarnitur (5) entspricht, bewegt, über die Weiche (1) in Kontakt mit dem letzten Waggon der Zuggarnitur (5) kommt, woraufhin das Schub-/Halte-Hilfsfahrzeug (3) mit der gesamten, durch das Seil (4) gewährleisteten Kraft das Schub-/Halte-Hilfsfahrzeug (3) durch direkten Kontakt des Schub-/Halte-Hilfsfahrzeugs (3) mit dem letzten Waggon der Zuggarnitur (5) anschiebt, so dass die Zugkraft der Lokomotive der Zuggarnitur (5) maximal ausgenutzt wird und zusammen mit der Zugkraft des Schub-/Halte-Hilfsfahrzeugs (3) die notwendige Kraft zur Überwindung des Rollwiderstandes und aller anderen Widerstände und des Steigungsanteils des Gewichts der gesamten Zuggarnitur (5), bis zum Erreichen des oberen Abschnitts der verbundenen Eisenbahnstrecke zur Verfügung stellt, und beim Erreichen des oberen Abschnitts der verbundenen Eisenbahnstrecke die Zugzusammensetzung (5) zu beschleunigen beginnt, während das Schub-/Halte-Hilfsfahrzeug (3) stoppt, wobei, wenn die Zuggarnitur (5) hinabfährt, das Schub-/Halte-Hilfsfahrzeug (3) vor der Zuggarnitur (5) beschleunigt, um mit der Lokomotive in Kontakt zu kommen, so dass der wesentliche Teil der notwendigen Bremsenergie von dem Schub-/Halte-Hilfsfahrzeug (3) übernommen wird, welche die Bremsenergie während der Abfahrt auf die Kraft der Zugseile (4) überträgt, die durch das Bremsseil mit dem Motorgenerator (6) des Systems derart verbunden sind, dass eine Umwandlung der mechanischen Energie in elektrische Energie ermöglicht wird.
  3. Verfahren für das System nach Anspruch 1 zum Schieben oder Halten eines Zuges auf steilen Gefällen einer Eisenbahnstrecke unter Verwendung eines Zugseils und eines Hilfsfahrzeugs, dadurch gekennzeichnet, dass, nachdem die Zuggarnitur (5) auf der verbundenen Eisenbahnstrecke mit starkem Gefälle herabfährt , sich das Schub-/Halte-Hilfsfahrzeug (3) im unteren Abschnitt der verbundenen Eisenbahnstrecke von der Zuggarnitur wegbewegt, sodass es die Geschwindigkeit in Bezug auf die Geschwindigkeit der Zuggarnitur (5) beschleunigt, um die Weiche (1) eher zu erreichen und sich von der verbundenen Eisenbahnstrecke weg zu bewegen, so dass die Weiche (1), nachdem das Schub-/Halte-Hilfsfahrzeug (3) sie passiert hat, in eine Position umschalten kann, in der die Zuggarnitur die Weiche (1) bis zur Eisenbahnstrecke durchfahren kann und den freien Zugang für eine andere Zuggarnitur für eine Berganfahrt gewährleistet.
