I was trawling through YouTube this evening when I came across this video, mainly showing library footage of Moorgate station in the 1990s. However one note of interest is that at the beginning, a 1959 or 1962 tube stock is stationed on the Met line terminating platforms with what seems to be a ribbon attached to the front and a "SPECIAL" destination rolled up.
Does anyone have any information on what this occasion was, and if possible the unit shown at Moorgate?
