This event was organised by the Great Western Society at Didcot to bring together the only three steam locos carrying the same British Rail blue livery during the preservation era. It was held on 5th April to commemorate the designers Nigel Gresley (loco 60007)and Charles Collett, (loco 6023), who both died on that date in 1941 and 1952 respectively. The third loco is the newly built 60163 Tornado not shown here.
Location: Didcot, Oxfordshire, England.
