The 1hr is true.

It's typical on conventional mainlines, but on very fast ones much less
so because price also comes into it. Rugby is not, for example,
primarily a commuter town (there are commuters, but that proves nothing
- there are commuters from far further away too).

Peterborough and Market Harborough[1] definitely, Grantham increasingly
so.
