Steve Davies, the NRM Director at the time, decided that to celebrate the 75th anniversary of Mallard’s record run, all six surviving A4s should come together for the ‘Great Gathering’. This amazing achievement generated huge attendance at the NRM and Shildon from across the UK and abroad.  This book was published describing Gresley’s A4 Class, and their amazing service on the East Coast Main Line and later in Scotland, bot forgetting that 60022 Mallard still holds the world steam speed record of 126mph, a record unlikely now ever to be beaten.
