Hi,I visited Upton Park Goods yard in 1973 and there were two signs at the entrance,one modern sign the other as mentioned was blue & white.In 1973 the main traffic was scrap tinplate off cuts.This was received from Metal Box Factories and reloaded into 16 Ton minerals for Llanelli & Hartlepool.There was also a few wagons of coal received every week for Hulbert Bros,Turp and Peter Burns.I have an interesting memo dated in the 60's requesting 2 brakevans for the Upton Park trip making it easier to run round at Gas Factory Junction.July 1984 seems to be a relalistic date for closure, this in line with the miners strike and the withdrawal of wagon load coal traffic in conventional wagons.
