A railway track barrier system that includes a barrier extending along a rail adjacent a switch having an upper edge adjacent a rail head disposed within a wash zone thereof formed of deflector elements movable relative to one another permitting railway vehicle wheel and wash contact during train passage without barrier dislodgement or damage. The refrigeration system may be configured to have a first stage suction line heat exchanger and a second stage suction line heat exchanger. Each of the two switching changers has the same switching cycle period and the striking phases of the switching elements of one of the switching changers and those of the switching elements of the other switching changer are made variable. In this way, the user can access software applications that can exactly satisfy hisher requirements in a more quickly manner.
