GWR Duke 3259 plus another set back out of the station at Aberystwyth. Note the concrete post GWR signals. The date is estimated, there appears to be several dark toplight vehicles so these could be in the pre 1921 crimson. I don't think it is post WW2 as there is no modern stock in this or the sister shot. Supporting this thre is no cab round window and a short vac pipe. This loco never had ATS.
