'The Burton and Ashby Light Railways 1906-1927' by Mark Bown - pub. 1991 by Reflections of a Bygone Age, states there was no opening celebrations when the service to Ashby de la Zouch began in 1906. There was a branch off the main line south to Gresley which opened the same year. Note that the bottom of the postcard is dated 27 August 1910 - perhaps this is an outing of some sort?
