37713 growls through Wressle station on 19 January 1998 with the 6E39 08:10 Mostyn to Hull Saltend empty acetic acid tanks. Saltend supplied acetic acid (vinegar) to both North & South Wales (Mostyn and Baglan Bay). Whilst I have a fair number of pictures of the Baglan Bay working, this is one of my few decent pictures of the Mostyn train. I have even fewer pictures of the third traffic flow, to Spondon, in the Midlands.
