Firsby was a junction for the Skegness line and the Spilsby line on their short branches from the main GNR London to Cleethorpes railway. During the summer months holiday passenger traffic, from throughout the country alighting at Firsby for the connection to Skegness, was substantial with hundreds and sometimes thousands of passengers passing through the station at a weekend. In the Victorian era most holidaymakers travelled by train and Firsby was one of the busiest stations on the East Lincolnshire Railway. The station was the major employer in the area and between the station master and his assistants, ticket office staffs, ticket inspectors, signalmen, porters, catering staffs, drivers, firemen, guards and track maintenance staff for three separate railway companies, several hundred people worked at, or from, Firsby station on a daily basis.
