Geismar is situated on the stub of the Northampton to Bedford line. About half a mile before you get to the Geismar site was a private siding called Hammer Steel, this private siding was laid in the early 1980,s to serve a steel stockholder, receiving wagonload steel from the Continent.
The sidings closed in the 1990,s the point work was taken to Geismar for constructing the run round loop.
The line was ballasted in a unusual way. In the C&W sidings at the station, a large number of Catfish, Dogfish and Mermaids were awaiting repairs to chute doors and mechanisms, unfortunately the couldn't be repaired as they were part loaded. Mysteriously, they were taken down the branch, unloaded at geismar site then taken back to the yard for repairs!
Everyone a winner, line and point work ballasted, wagons repaired and the train crew football club receiving a new strip sponsored by guess who!!!
Those were the days
