Cycle Train-ing

Sorry, but Friday's ride home had a railway theme!

This is a strange structure to come across in the middle of the woods; A large concrete cylinder topped with fearsome metal spikes and barbed wire. Your imagination could run riot with you, but the sound of a passing train below gives the game away - it's an air shaft for the railway tunnel below.

This is Harmergreen wood, just north of Welwyn Garden City, which sits above the main railway line from Kings Cross to the north.

I imagine that it's a popular place for the local dog walkers, but on an afternoon like this it was very tranquil and I didn't see a soul. Which is probably a good thing because I found some interesting 'single track' and went bombing down it like a loony!

Next stop was Welwyn North station to get a shot of the tunnel entrance, which is actually two tunnels with a very short cutting in between them. The date above the tunnel says 1859.

I couldn't finish this without a picture of the viaduct at Digswell. Those crazy Victorians huh!
