in 2014 the engine masqueraded as d 893 for the centenary of the thompsons foundry in castlemaine. while most of its fittings were retained for the day, the number, letter and builders plates were swapped for the occasion. notably, the first d built by thompsons was in fact preserved, having been converted to d 640 in 1937 then renumbered d 688 in 1964. it is displayed on a plinth in swan hill, and more recently returned to its previous 640 identity.
