Some help was required with this one. 25187 trails another class 25 on a passenger train at an unknown location. With the GWR lower quadrant signals and the single line ahead I expect that this is the line from Shrewsbury to Pwhelli / Aberystwyth line but which station? Thanks to help from the members on RMweb the location has been identified as Towyn.
