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.

An integrated electromagnet comprises a magnetic yoke and magnetic poles in two rows. An axis of magnetic core in the magnetic pole is perpendicular to the magnetic yoke. The magnetic poles comprise first and second magnetic poles that are arranged alternatively in a row. The first magnetic pole in any row is adjacent to the second magnetic pole in the other row. The first magnetic poles in a row are connected to a one-way output controller and the second magnetic poles in a row are connected to a bidirectional output controller. In a guiding state, the magnetic poles in a row have a same polarity, and a polarity of the magnetic poles in one row is opposite to that in the other row; current output by the bidirectional output controller in a braking state has direction opposite to current output by the bidirectional output controller in the guiding state.
