Indeed. It may be unlikely, but it’s still a sorry state of affairs for the mainline between our two main cities. Why do we have to accept such substandard infra?
The solution is called HS2, which will remove the current fast-line traffic from the Rugby route at least as far as Crewe, leaving more local capacity.
Most of the WCML was 4-tracked up the Trent Valley (and beyond as far as Winsford) by the LNWR in the 1890s, mostly through rural areas.
But the Birmingham loop has had heavy encroachment of property and industry making it hugely expensive and disruptive to widen.
There was an extra 2-track route built through the area in 1899 (the Great Central), though it managed to avoid Birmingham and is now closed.
You can argue this capacity investment should have gone into widening the WCML and Midland routes instead, but that's what was built (with private money).
BR was told to downgrade the GW route from Paddington to Birmingham in the 1950s, to allow the Euston route to be electrified.
Some of that capacity has recently been reinstated, but not to the same level, and not from Paddington.
