Does 166210 have an aversion to front end numbers? Over a year after seeing it with virtually no numbers at Chilson, it looks little better here at Culham on 27 April 2011, as it heads southwards with the 1P53 15:01 Oxford to Paddington First Great Western service. I'm not quite sure what useful purpose the warning notice in the foreground serves, as there is no public footpath crossing at this location.
