Following the service disruption in the heavy snow, for Wessex, of early March 2018 that culminated with an evening Waterloo - Weymouth service being stranded on Christchurch Bank until the next morning Network Rail have recently allocated a Snow and Ice Train at Totton.
The first running, if information is correct, 3Y88, Totton - Weymouth and return. was on Friday 13th with further runs on yesterday and today.
I saw it twice on the 13th near Beaulieu Road and the down run and later after returning to Totton Yard.
If anyone has any knowledge of the wagons involved it would be appreciated.
