37511 Stockton Haulage passes Portway on 15 March 1989 with what is presumably the 6E47 11:15 Cardiff Tidal to Tees steel. I say presumably, as although running at the correct time, 6E47 was usually a pair of 37s. The empty HSA wagons for scrap traffic were more common on this service that the sheeted steel wire wagons, as most of the time this train conveyed empties.
