The layout of Habrough reflects the unusual YY arrangement, as shown on this simulation (it has been changed now), which accounts for the low maximum speed of 20 mph through the station.
The signal on the Great Coates side of Grimsby Town Station really was on the "wrong" side of the track. It allowed drivers to see the signal as the train approached Grimsby Town, as this would have been impossible if it were on the “normal” side of the track.
The mainline Station at Frodingham (Scunthorpe) is on the site of the original station, close to "Scunthorpe" station on the NLLR. The modern station was built later close to the over bridge to the west of this station, and was named "Scunthorpe and Frodingham." I believe it is now simply called "Scunthorpe."
The stretch of four-track line between Brocklesby Junction and Barnetby used to be one of the busiest stretches on the whole of British Railways! Over 20% of ALL modern UK rail freight traffic starts or finishes at Immingham
Although difficult to believe, the North Lindsey Light Railway saw the very heaviest trains on the whole UK rail system! This occurred when iron ore mines were opened up near the villages of Thealby, Coleby and Winterton (after the time of the line as depicted in this route).
Immingham is shown as in the 1930s, before the importation of oil resulted in many oil storage tanks being sited on the dock estate. "Hedborough North" is a modern depiction of Immingham.
The bridge south of Thornton Abbey was removed many decades ago .... but it’s nice to show something that virtually everyone has forgotten about!
The three-arm signal on Firsby Station down platform (looking the “wrong way”) is for trains to (reading from the top signal downwards) Skegness, Boston, and Spilsby.
I have tried to put in a few details - mainly of people - that users may spot only after passing the same spot many times. Some of them represent real people as they may have been, (including my grandfather!) and at least one is inspired from a scene in an old postcard!
