I was more curious about where the rumors actually originated? After doing some research, it looks like Virgin is exploring the idea of launching trains to compete with Eurostar. Now, if these new Virgin trains were equipped with third-rail capability, theoretically they could run on the UK’s mainline railway network and utilise different routes. It also mean train stations would have to build passport control terminals to run this service.
Of course, this is all purely fantasy it’s unlikely to ever happen. Still, it’s such a shame that continental rail routes don’t extend further north into the UK. The Channel Tunnel has never really been used to its full potential, which is a missed opportunity in my opinion.
