SR MN 4-6-2 No 35008 Orient Line with 'Devon Belle' headboard in c1950. One unusual operational feature of the "Devon Belle" was that it stopped at Wilton in each direction, where it changed engines there rather than the more normal Salisbury engine stop. Just six minutes was allowed for this manoeuvre in each direction so could it be here?
