I worked at Shellstar/UKF/Kemira for 40 years.
It's latest owners have recently closed the site, but it was a long time ago when they stopped using 50 kg bags.
The pallets for road transport had 18 bags on, reduced to 15 bags to fit in the railcars.
600kg and 1 tonne bags came into use which had to be lowered into open wagons.
The track from Ince to Mouldsworth junction was lifted many years ago followed by the track inside the factory.
Class 47's were a common sight and occasionally a pair of class 20's would turn up.
In the early days phosphoric acid was imported by rail and ammonia was exported by rail, I don't recall seeing any models of those.
