BR flag at Cardiff Central, UK
Despite still being the accepted symbol for "Railway" "Station" and the symbol promoted by ATOC under the "National Rail" banner, it is rare to see the BR "double-arrow" symbol so prominently displayed nowadays. There is some thought, however, that the SRA are pushing operators to ensure that the BR symbol is still clearly displayed near station entrances.
