LONDON -- It's one of the rainiest British winters on record. So some London commuters were surprised to hear their trains had been delayed because of the sun. Rail operator Southeastern tweeted Tuesday "we had severe congestion through Lewisham due to dispatching issues as a result of strong sunlight." The company said low winter sun was hitting monitors at an angle so drivers could not see them. Commuters are used to hearing an array of excuses for frequent delays.
