That would be the hybrid HST / class 91 MK3 sets early on in their life wouldn't it? But also slightly earlier the 17.36 King's Cross to Peterborough at the time they were first introduced; often a scratch rake usually of Mk2 carriages. It was generally diagrammed for the class 89, but it also saw the first passenger use of the class 91s.Thanks. How about not on a Mk4 set?
