Should be back in service tomorrow. But every Wednesday at the moment is a staff refresher move to/from Peterborough.I did happen to spot 91111 on the rear passing through Leeds earlier. First Class at the front/county end, so not sure if it's being pressed into service expediently or if it will be turned somewhere.
