So what is all of the work going on the the field on the down side of the line between Langley and Iver? I was hoping it was related to this scheme, but if planning hasn't been approved then presumably not. This got the go ahead 5+ years ago - disappointing that planning hasn't even been gained yet for what is more or less a totally underground railway.
I think that's Cemex's "North Park" quarry. They got approval in 2016/17 (Buckinghamshire County Council application CM/51/16) to extract aggregates, then refill with ... other less useful stuff. They made a big point in their application that, once
NR» had buried a railway, extraction would be impossible (the portal is in the middle of the Cemex site). So they proposed a six-year extraction phase, followed by 3 years of refilling, which could be combined with NR building their tunnel. The approval was conditional on cooperating with
WRAtH▸ .
I guess that would mean building the tunnel above ground, then raising the ground level so it becomes a proper tunnel. How Cemex are getting on in terms of timescale I don't know, but I doubt there's much chance of WRAtH being delayed by it!
