Paris to Marseille - 3hr 20 (its nearly 500 miles)
Edinburgh to London - 5hr (its 400 miles)
Measuring HS2 in terms of Birmingham to London is silly imo, thats just phase 1, phase 2a gets to Crewe, 2b joins in Manchester and Leeds. The NRP then joins the East Cost to the West
Our railways are an antiquated mess and yiou can keep chucking money at them for decades and decades and they won't get much better
Capacity needs greatly increasing we need to get a whole heap of heavy good vehicles off our roads, go anywhere else in Europe and you don't see anywhere near as much HGV traffic on the roads
