GB Railfreight 66746 is currently being repainted by Arlington at Eastleigh Works: link. This loco has been carrying the current GB Railfreight livery for some time already (see image), so we expect the loco will be outshopped in a bit more special colour scheme soon.
Updated: It has been confirmed that 66746 is being repainted in a Royal Scotsman livery because GB Railfreight has taken over the contract to run this train.
