If you maintain similar stopping patterns you can get higher than that on a two-track railway - metro services can do 25tph,30tph or even slightly more. From December the west coast mainline is bringing in a roughly pre-covid timetable. The railway is a 4 track railway, but looking at just the fast tracks leaving Euston, there will be 13 departures an hour on the fast lines 3tph Manchester 3tph Birmingham fast 2tph Liverpool 1tph Chester and North Wales 1tph Glasgow 1tph Crewe via Trent Valley stops 2tph Birmingham via Northampton (switch from the fast lines to the slow lines after about half an hour) None of these are high speed - I'm currently on a train to Manchester and my phone says we're doing about 125mph (200km/h). HS2 is a more reasonable 200mph. To be fair, Accela Washington-New York-Boston is more akin to the London-York-Edinburgh services which are only 2tph, or 31 trains per day (44 run as far as York, but only 31 continue to Edinburgh) The frequency on the WCML can't be higher as some of those trains are non-stop as far as places like Stoke, Crewe, or even Warrington (about 90-110 minutes out of Euston), where others do stop at places like Watford, Milton Keynes and Rugby.

(In addition to the 5 trains per hour to Birmingham above, there is another one or two from a different London station - Marylebone, and there's a handful of additional trains from Euston to Edinburgh via Birmingham)
