[edit]Description2017 at Bristol Temple Meads - signal B38 and B40 renewal (face).jpg |
English: Engineers replacing the signals at the west end of platforms 6 and 8 at Temple Meads station in Bristol. The previous signals had been installed in the 1970s and used three-aspect filament bulb signal heads. Their 2017 replacements have multi-colour LED signal heads which can show any of the three colours (red, yellow or green) from a single lamp. |
