A train describer display apparatus displays train description information as a bright-up pattern of alphanumeric characters on the rasters of small cathode ray tubes by stepping a shift register operating with serial read-out in synchronism with the scanning circuits of the cathode ray tubes. The displayed data is changed by applying new information to a selected shift register from a store which is filled from a data highway, the data highway also operating in conjunction with an address highway to determine which cathode ray tube out of a selected group of cathode ray tubes is to receive a modified display. |
