In the past there was talk about under powered road vehicles, but no definitive list, so they will be listed here.

All lorries can use twice the kN
Mail variants are currently capable.
Thank you very much - that is very helpful. You write that they could use twice the kN - does that mean that you suggest increasing both the power and the tractive effort?
yes. Since trucks use tyres, their tractive effort per driving axle can far exceed what is possible on rail. The main limitation is how much power and torque can be fed into the mechanical gearbox before it explodes.
Based on my research....
Modern trucks, at least from the 80's, would have somewhere around 250hp to 650hp with turbo chargers.
Slightly older trucks, say between 50's and 80's would have had anywhere around 100hp to 400hp.
I have now made the suggested amendments on my Github branch. Thank you for this!
