Abstract

An information module system (40, fig 2) for use in a vehicle with an electrically powered brake control unit 30, which brake control units has a date store to retain operational date and is connected to the information module via a data link. The information module is provided with a bistable display which is adapted to display operational data even when the vehicle is stationary and powered down. This is particularly applicable in the case of freight wagons which have no independent power source. The bi-stable display may be a cholesteric LCD (Ch-LCD) display; the data may be in the form of a barcode. The system may have a temperature sensor and may modify the data sent when the temperature is below a predetermined temperature. A display screen may have a UV filter, be scratch resistant and have an internal dessicant to prevent condensation.
