The FA is laying on 120 coaches to help United and City fans get to the FA Cup final at Wembley next month.
No trains will run between Manchester and London on June 3 due to planned strikes by National Union of Rail, Maritime and Transport Workers (RMT) and train drivers’ union Aslef.
The strike has thrown into chaos fans' travel plans, prompting both clubs to lay on extra coaches to London for the first ever Manchester derby in a final.
