'...an underground HSL through Birmingham...After all, that was the engineering solution to bring Eurostar to St Pancras!' And although tunnel boring machines are always expensive beasts, costs (such as diverting existing underground utility services, etc.) can be minimized by tunnelling below existing surface rail RoWs, which is what was done for much of the route into St Pancras, which lies below (successively, east to west) the Tilbury loop, the Barking-Gospel Oak line and the North London Line. |
