Let's look at the 'balance of probabilities' thing
Approximately one million commuters to London each day. You quoted 11 other cities, most of which are less than 1/10 the size of London either in standing population or commuting population - therefore on the balance of probabilities, it is far more likely that a commuter, particularly a train commuter, is commuting to London.
Do try to keep up.
