The channel tunnel needs to be open at night, night bus is already a great way to travel benelux/rheinland to london but imagine a Berlin/Barcelona/Milan to UK night train it'd be great

They’d also need to build and certify rolling stock to the tunnel’s safety requirements, which are stringent, and one of the reasons why no other companies have offered services through the tunnel.

When the tunnel was built, they actually did plan sleeper train services between Scotland and Paris/Brussels, and commissioned compliant sleeper carriages. The service ended up never happening, and the carriages were sold to Canada.
