Light Trails in Black and White

Brief

The focus of this contest is light trails, achieved through the use of long exposures. I want to see how you can show light trails, but in a unique way by showing images in black and white only, so please do not enter any colour photographs. There can be any choice of the main subject for example cars, trains, planes or handheld illuminations. Experiment and challenge yourself to see what images you can capture, especially if you have not experienced this type of long exposure photography before.
