  • Apparatus for determining the signal term to be transmitted to a railroad traction vehicle
    Patent number: 4381094
    Abstract: The signal term to be transmitted to a railroad traction vehicle is formed in a signaling system in that each element, from a destination element back to a start element has a respective top speed assigned thereto as an identification. The identification is transmitted element-by-element back to the start element and is devalued during relaying thereof when the identification is greater than that prescribed for a travel path element having a lower assigned top speed so that the identification received at the start element indicates the top speed admissible for the route. The admissible top speed is then converted into a corresponding signal term.
