Idea of connecting Northern cities like Manchester, Liverpool, Sheffield, Leeds with great public transport. (Frequent, electrical, large size for plenty of passengers).
Turning them into a megalopolis like Randstad in Holland (Rotterdam, Utretch, Amsterdam, The Hague, and smaller places).
Heard the comparison to Randstad first in: Analysis - Unequal England - BBC Sounds.
