1.  The Invention

 

Title: Controlled separation of return network powered from two sides
The problem the inventor(s) wanted to solve Limiting
stray currents during operation as well as balanced distribution of tensions between rails and the earth (surrounding environment).
Description. To limit stray currents track sections c
ontaining rails founded on track ballast are separated from track sections  constructed in the ballast-free technology. In order to avoid the adverse phenomena of electroerosion of the connector and wheel rims as well as emission of electromagnetic interferences, the isolation connectors ought to be closed for the time of the train's ride.
Advantages Limiting stray currents as well as electroerosion of the connector and wheel rims
.
Stage of development. Design of electric circuits .
Documentation available: Yes
   brochure.
