Passengers using Chiltern services in and out of Marylebone on Tuesday faced overcrowding and cancellations due to a shortage of trains.
Marylebone is the only mainline station in central London still to use diesel trains. On Monday night Chiltern Railways warned that services to and from Oxford would be reduced from every 30 minutes to one an hour because of fuel supply issues at one of its depots, which meant that not enough trains were available to run on Tuesday.
