UK Signalling: Temporary Speed Restrictions on the ECML (Train Sim World | tutorial)

Time to discuss the signalling and signs used with temporary speed restrictions (as opposed to permanent speed restrictions) in the UK, after they have been introduced in at least one scenario on the East Coast Main Line.

Full Hot Seat scenario on the BR Class 801 'Azuma' Hitachi A-Train, running from Doncaster to Peterborough on Dovetail Games' East Coast Main Line DLC, with a short tutorial discussing temporary speed restrictions (21:20), including emergency speed restrictions (24:23) and blanket speed restrictions, and the corresponding signage.

Signs of this kind can also be found in the "Water Works" scenario of the "Glossop Line" DLC (with actually enough braking distance after the warning board, but also incorrectly used "R" sign and SPATE indicator, AWS magnet still missing).
