- the rail system prevents lateral movements of the vertically movable components.
- the vertically movable components can be moved from stop to stop along the rail system by a drive device.
- the position information can be provided by a shaft information system.
- a magnetic tape can be arranged parallel to the rail system.
- a reader for the magnetic tape can be arranged on the cabin. Height information can be stored magnetically on the magnetic tape and can be read out by the reading device using at least one magnetic reading head.
- the height information read out can be compared with stored height information of the bus stops.
- the drive device can initiate a braking process and bring the car to a standstill exactly at the bus stop.
- Other functions can also be controlled or triggered on the basis of the height information read out, such as initiating an opening process for car doors shortly before a car door is reached stop or leveling out differences in level while the car is waiting at a stop.
- the shaft information system Due to the magnetic tape, the shaft information system has high material costs, among other things.
- the permanently magnetized magnetic tape can be replaced by a locally magnetizable tape.
