Falling usage caused passenger services to be suspended in 1939 just as the Second World War began and they were never reinstated. A goods train service for grain, potatoes, livestock and other agricultural products continued through Firsby for almost another twenty years. Goods including petrol, paraffin and coal continued into Spilsby via the rail link until its closure on 30 November 1958. The Spilsby station building has been demolished but other buildings still stand, and in recent years have been used by an agricultural suppliers as a shop and store with new sections added. Between Firsby and Spilsby most of the old track route can still be seen in aerial photographs, marked by the avenue of trees and bushes, with only 5% ploughed out into fields.
