Euan, is a Caledonian Railways 812 class built in 1899 at the CR's Works at St. Rollox, where he was primarily used on Light goods work by the Caledonian for may years. then in 1923 Euan was put into the hands of the London Midland and Scottish Railway where he was re-numbered 17566, and being painted in Goods Engine black, Though he wasn't a fan of Goods Engine black, he brushed it off as just another day on the railway. in 1948, he became part of BR (Now Numbered 57566) Euan didn't like BR's Agenda as they were; according to him "Idiots who daydreamt like hooligans". He spent his last workings years on BR before being retired and preserved. Though Euan is a Grumpy engine, he's not always that way, He always enjoys a job well done without fuss, and proves that he is still really useful.
