To settle arguments here, can anyone tell me what are the fastest
scheduled long distance trains in Britain?

They don't exist, is the simple answer to your question.
The shortest journey time between, for example, London and Edinburgh (400
miles) by train is 4 hours 19 minutes. That's an average speed of (only)
92.6 mph.
I think even Turkey now has faster trains than we do here in the UK (not to
mention the rest of Western Europe).

Are there any other trains as fast as the Chunnel train?
Nope.

How is timekeeping on the fast trains?
Reasonable.
