On 20 April 2012, at 08:44, an East Midlands Trains Class 222 unit pulled into Nottingham station where both the driver and station staff noticed smoke coming from underneath one of the carriages. The engine underneath the carriage had caught fire from overheating – which occurred due to day-to-day grime which had built up underneath the train and then been heated up by the movement of the wheels.

Using these trains on the Belfast-Dublin line was one of a number of options, which also included the purchase of additional 22000 Class railcars or cascaded coaching stock. In the event, the trains entered service with MML providing the fast services from London to Nottingham, thus releasing High Speed Trains. The trains would have required significant modification to be used by Northern Ireland Railways, including reducing each train from nine to eight cars (the maximum length of stations on the Belfast-Dublin line), and converting them from standard gauge to Irish gauge (5 ft 3 inches). Grand Central Grand Central, on the announcement of its open-access operation to Sunderland in the summer of 2006, planned to run its services using five Class 222 units, with the intention of starting by
