00.21 secs - after some research I reckon Tornado is at Melksham on 26th June.

Yep, it's at Melksham; 26th June sounds about right. First call by a steam powered train (to my knowledge) since the station re-opened in 1985. The one (and only) call by a
heritage steam loco was on 23rd April 2014, by Braunton on its way to Stratford-upon-Avon.
Please note that the September 2016 "Steam Dreams" train that calls at Melksham on its way to Kingswear will be diesel hauled on the TransWilts.
