The two models don’t achieve the same though. They almost might if everything runs every 15 minutes, but at less than that - the usual 30 Minute Standard - the Swiss way will achieve significantly shorter overall journey times especially if there is more than one connection involved.
I don’t dispute that it comes with a huge bill and that not everyone will want to pay it; for the U.K. it would probably unaffordable (not because you are so poor but because the country is so large, and as you rightly pointed out your stations don’t really lend themselves to Expansion) The Swiss do however, as they have stated several times at various referenda.
I never suggested the two models achieved the same thing. The important thing is either model would represent a significant betterment on the GB model of today. If GB is bronze (if that), Switzerland gold, Netherlands silver (at least silver plus in my book), then silver is a good and realistic goal to aim for.
Just like the Netherlands, GB has a lot of semi 15-minute nodes - 4tph on one side splitting towards 2tph on the branches. The Swiss would tend to flight the 4tph to ensure both the 2tph branches connect well (like Spiez), whereas the Dutch would tend to do the opposite (like Roermond). Places like Stoke-On-Trent can do a Roermond with relative ease but doing a Spiez would be too expensive, and the relative strengths of the various markets favours giving Stoke - Manchester an evenly spread 4tph fast service over having Alsager connecting to everything.
The Dutch model is not only more suited to the GB geography, it's also Treasury friendly.

Exactly my point. These were not minor upgrades, they involved significant spends. Unfortunately in the UK we don't seem to like spending significant sums to get major improvements, we seem to prefer spending as little as possible. Hence all the arguments about tweaking the existing network rather than building a high speed line.
If we are 'only' going for the Dutch model then there isn't an inherent necessity of making trains slower. This only involves regularising / standardising services, not making them wait for each other.
The kind of 'tidying up' might involve
- Moving everything around the clockface to a common symmetry
- Not trying to run everything across Ordsall Lane Junction. Let the 4 track formation through Manchester Victoria function as two independent systems, and use the capacity created to run a proper service level over the Ordsall Chord so north and south Manchester can be done with a simple interchange
- Not having Crewe - Stoke worked by two uncoordinated services with zero regard to symmetry. Instead have a standardised strict half-hourly Crewe - Stoke - Stafford (- Birmingham) service
- Tidying up station throat workings at London Victoria and eliminating interworking between fast and slow sides
If some of these involve an element of cost, then it would be within the typical UK affordability envelope.
Where we might go for the Swiss model - Swiss enhancements mainly involved bypassing slow twisty mountain railways with 140-160km/h cut-offs (with the exception of the 200km/h Olten - Bern / Solothurn). Britain's starting point is 90-125mph (140-200km/h) main lines so we can actually afford a bit of slack compared to Switzerland (in a post HS2 world, realistically). In other words what the Swiss had to spend money on, we already have, and we ARE spending big money on HS2 (however mismanaged the project is).
Then comes the element of luck.
Chester - Shrewsbury - Hereford are ~55-minute journey time sections without having to do anything. You get a Swiss takt entirely for free. Then you have Nuneaton - Tamworth - Lichfield - Rugeley where again you get takt nodes for free just by coordinating Up and Down service timings. And it just happens that Nuneaton - Coventry - Leaming Spa have 'takt ready' running times too.
