The LNER attraction to racehorses produced some pretty exotic names too.
I have a great liking for the racehorse-name theme: find it a stroke of genius on the part of whoever thought of it.
Loco names using racehorses would have made commercial sense for the LNER. Three of the five "classics" were in LNER territory, the 2000 Guineas and 1000 Guineas at Newmarket and the St Leger at Doncaster. It also had other big race meetings such as the Dante and Ebor meetings at York.I agree with @Calthrop that the LNER choice of racehorses as a source of Pacific names was excellent
Race traffic was big business for the LNER and it wasn't just about moving spectators, it was about moving the horses too. An example, not linked to race meetings, is the horsebox trains that would run to Holyhead after the yearling sales at Newmarket to take horses to Ireland for training.
