No, the MK5s were specced and have been approved for 125mph running as proven by the streamlined DT, so a new class of streamlined electric locomotive was always in the pipeline.
Back on topic, I find it fascinating how Network Rail has software that can translate drawings into a visual representation, the accuracy as shown at Ulleskelf is excellent! Well done to whoever worked on that, I wasn’t aware of such software until I watched the video. Go to 23:48 to see what I’m on about.
Various digitisation design software programs exist, and have done for some time (getting better and easier to use as time goes by), the software they are using was referenced to busy after that visualisation you talk about. Not sure if they said the product name but they referenced the developer Bentley who have been developing their CAD system called MicroStation for several years now.

20 years ago it would have taken days to get anything much more than a basic wireframe model, now (at least in the highway design tool we use) you can design with a 3d orbit tool as soon as you create an object so you see how things interface.
Also with the speed of the development of computers, what used to require high end workstations can be done on fairly modest computers (a bit slower, but it's possible).
They also talk about being able to identify what's at any given location, again many are doing this with their BIM software. With it possible to move around buildings in a VR type environment and be able to identify all the elements which go into constructing that building. The theory is that you could tell exactly where something runs within a building so you should be able to still a hike safe in the knowledge that you're not going to hit structural features or cables or pipes (of course what's designed and what gets built can differ).
