5. Conclusion

There were carried out measurements of the mechanical claim, of the horizontal and vertical movement of the switch tongue, once with the installed system EKOSLIDE and once without it.

The movements and the mechanical claim of the switch tongue are influenced by the technical condition of the switch, the quality of the sleeper ´s underlying, of the parameters of the test construction and of the place of the switch.  These parameter determine the initial position of the movements, like mentioned in the measurement documentation.

It can be asserted that the changes of the tongue movements after equipping the switch with EKOSLIDE were minimal and don´t influence the passing of the train.

The mentioned facts are in accordance with the report [1] and confirm, that EKOLSIDE can be installed at the tracks with normal train traffic of the Czech State Railways up to a velocity of 140 km/h.

Suggestion:

In case that the velocity of the passing trains is essentially more than 140 km/h, I suggest to carry out a new measurment of the dynamical reaction and the reaction of the switch closing with the equipped EKOSLIDE.
