Was this done in conjunction with RSSB? Just that the opening titles (Semi-Transparent Train) look very similar to the opening of the RED Safety Videos.
This was due to Temporary Speed Restriction information not being relayed by the signalling system. It was a fault with the system designers (Ansaldo) coding which displayed incorrect information showing that the restrictions had been loaded after an automated restart. Ansaldo are now a part of Hitachi and the software has been thoroughly tested, as well as support from RSSB and AIBN. Let’s hope it doesn’t happen again, but this system must be adopted for the future of the railway and to improve competitiveness compared to road freight 🚂
