Abstract
An eddy-current rail brake device includes a row of magnets, a supporting member, a case, and a lifting device. The row of magnets includes a plurality of permanent magnets that are arranged in a traveling direction of a railroad car. To the supporting member, the row of magnets is mounted. The supporting member has magnetism. The case houses the row of magnets and the supporting member and includes a bottom portion that faces the row of magnets and is non-magnetic. The lifting device raises and lowers the supporting member inside the case while the row of magnets is kept facing the bottom portion. The eddy-current rail brake device can prevent or reduce adhesion of a foreign object and can be reduced in size in a right-left direction.
