It's called a 'Yellow board' or 'P4 protection', which protects workers on the track (P4 is the rule about using them). The yellow side means you are entering their work site and the black cross means you are leaving it. <br />All of that is just an educated guess, the FR uses identical boards but smaller, so there's a good chance that that is what they are for. <br />No idea what the frame is used for.<br />Huw Einion Joneshttp://www.t-m-r.blogspot.comnoreply@blogger.com
