The mobile crossing is designed for use on existing two-track tram lines with a covered superstructure on straight runs without abrupt gradient changes. It is also used as a temporary and mobile reversing bay for bidirectional cars. Two-way traffic can be temporarily conveyed on a single shared track by using a right mobile crossing and a left one at the same time. The mobile crossing is used during construction works on tram lines.
