This is a project designed to last for centuries. We’re not even fossil free yet and already seeing days of negative electricity cost thanks to renewables. In 50 years the extra energy cost is going to be a rounding error. Locking ourselves

High speed rail does not need to be straight! You can get away with 6km radii at 360km/h on dedicated passenger lines. The high power output of the EMUs they’ve selected and all new OHLE power supplies mean that trains can accelerate a
