A Curious Structure On The Western Curve

The picture shows a rather curious white corrugated structure covering the Western Curve at Dalston Junction.

A White Steel Tent at Dalston

When I first saw it, I thought it was some sort of protection for concrete, whilst it was drying.

But it would appear that it’s the ventilation for the railway tunnel under Kingsland High Road.  It is designed so that the prevailing westerly winds will draw the air out of the tunnel.  I think, it’s also designed to work in case of fire.

This looks to me, like a classic case of very sound passive engineering.  An active solution with electrically-driven fans would be a lot more complicated and expensive.
