No problem with the identification of this loco! Someone has crudely scrawled 428 on the front end of 31428, seen here passing Glazebrook on 2 September 1987 with the 1E36 09:45 Liverpool Lime Street to Sheffield service, a working that in previous years would have worked through to Hull. These trains went over to unit operation shortly afterwards, and once again with hindsight more effort should have been put into photographing them before it was too late.
