Abstract (en)

[origin: WO9747814A1] The invention concerns a box-type sleeper for points fitted with heating elements (14, 17). The heating system can be accommodated better, in particular the reliability can be increased, by virtue of the fact that the box-type sleeper is closed and has at least one inlet aperture for several heating-element leads (12, 13).
