This is actually the lights from two cars, one after the other. I found that one car wasn’t actually enough to provide enough light to balance the streetlight. Fortunately, two cars turned up, right on cue. This shot is actually taken just down the road from a similar long exposure of a train that I put up last week. As the road turns a corner where the streetlight is, there is a roadbridge that crosses the railway. That shot was taken from the section of footpath just out of view about a month after this one.
