Sound and pacing are crucial to this claymation film which documents the wet, lonely stand of a solitary enthusiast, trying to "spot" the numbers of trains as they speed by.

The film presents vividly the cold and passing of time as the problems mount: the wrong platform, trains that are travelling too fast for identification. The pitter patter of rain is perfectly matched to the dank scene of a deserted railway station. But our hero's greatest problem is still to be disclosed... Finally all is solved by decisive action, but even then there's a string in the tail.
