After having explored nearly every corner of the main Underground network, my attention turned to other bits of the network. This being mainly the Overground and Docklands Light Railway (DLR). Both of these sections of the network are less interesting, as they are mainly in the open air. No long tunnels, no ghost stations to seek out. The Overground crossings of the Thames River are by bridge, apart from the oldest tunnel in the network, the Thames Tunnel which we'd explored. The only real points of interest on the DLR network were the short tunnels under the River Thames and a tunnel into Bank station.

The tunnel from Woolwich Arsenal to King George V station has one open air station, and one subterranean station at Woolwich. Not wanting to have to run back, we would need to enter at the subterranean station, and exit at the surface station. Entering the subterranean station was a little tricky, but no big deal. Kev looks up at Marta coming down.

I walked up to the station, where a banging could be heard in the distance, so didn't get too close.

Looking the other way the entrance to the tunnels. Marta sits on the right getting a snap. In the centre just above the fans sat our next problem. Were the cameras live monitored, motion activated or recording or only used during service. There was only one way to find out, and we ran past as quick as we could.

The tunnel curved for ages and we passed a couple of exit points to the surface, this being one of them.

There were also a couple of ventilation passages

I'd originally estimated the distances as 800m from an online map, however as the sign below shows, it was more than double this, as 2000m! We'd only done a quarter of the route. We didn't know if swarms of cops were surrounding the stations either side, and didn't stop for more than a quick picture.

Having crossed under the River Thames, this was a shot looking South to where we'd come from.

The other side of the camera from the above shot, the tunnel starts curving up to the surface station. There was less of a curve on this side, a bit like a J shape.

Kev and Marta had gone on ahead and exited already, as I was coming up the rear taking more photos. This was the exit from the tunnel. On the right wall in the distance sits a camera looking at me. Thankfully no cops though, phew!

The entrance to the tunnels on the North side of the river.

Got wood? The wooden dividing walls on the approach to the station. Over the wooden fence on the right, is City Airport.

The station is unmanned at night, watched over by an array of cameras. So face masked up, I ran out and into the night. Thanks as always to Kev and his rope skills, and to his wife, Marta for crazy input!
