Notes :
(1) Gordon Lacy comments: This was advertised to BR (ER) staff as "The schedule 
is designed for Driver training purposes, stopping and starting at intermediate 
stations and reaching high speeds between stops". Booking Office staff and 
representatives from local papers were invited to 'sample' the then new HSTs. 125 
mph was achieved before Scrooby on the outward run, but having  braked to 7 mph 
at Retford on the return, we appeared to have 'lost' one engine - so much for my 
first ECML HST run!
(2) Gordon Lacy also comments that the booked timings "applied all week" - 
confirmation of which dates this HST ran is required (and was it the same set on 
all runs?). Gary Thornton was at St Neots on 2nd December and photographed an 
HST set passing through both north and south - possibly 254004 - was this the 
same run?
