Ghost Train

I snapped this picture of a train arriving at Oxford Circus station using a clever app for the iPhone called SlowShutter which gives you control over how long the camera stays open collecting data, exactly the same as using Shutter Priority on a DSLR.

I like this though - I always find the Underground a slightly spooky place and this looks exactly like the kind of ghost train I could imagine running the tracks at night when no one is there...
