I noticed that they're doing some work at Hornsey station, on the Harringay side.
What's all that about? One idea I had, although I hope I'm wrong... involves these guys:
I know that a big reason they wanted that site is because the government wants them to rail the raw materials in. The trouble is, the south bound side of the tracks is on the other side from the factory and I assume the raw materials are not coming from King's Cross. Could they be building a road in here to allow trucks to take the raw materials from the train, on the ladder side, down Wightman road, Turnpike lane and then Tottenham lane to the factory?
