On the final days of semaphore signalling prior to the December 2015 North Lincs resignalling project, 66155 takes 6H60 (Immingham HIT to Drax) from Immingham Docks to Heywood Junction taking in the semaphore signals of Barnetby and Wrawby Junction.

Our journey starts at Immingham West Junction and we traverse the junction from the Down Killingholme branch towards Immingham Humber Road Junction where we continue to Brocklesby Junction via Ulceby Junction.

From Brocklesby we join the Down Cleethorpes towards Wrawby Junction via Barnetby. At Wrawby Junction we take the route to Scunthorpe on the Down Scunthorpe via Elsham, Appleby and the infamous Santon Bank where we require all 3000 BHP available to crest the summit at 12mph after hitting the bottom of the bank at 50mph.

After Santon Bank we head down in to Scunthorpe passing the massive Tata Steel blast furnaces and rolling mill and then head up the hill towards Scunthorpe Station. Once over the brow of the hill at Scunthorpe, we coast down Frodingam Bank towards Gunhouse Loop, keeping the speed at a steady 30mph for the heavy axle weight restriction on Frodingham Viaduct, then the line climbs out of the dip (still coasting) towards Althorpe station and Keadby Canal sliding rail bridge.

Passing over the sliding rail bridge at Keadby Canal doing 25mph, we continue on the Down Main towards Thorne Junction running parallel to the canal nearly all the way. As we pass Thorne Junction, we are routed on to the down slow line to allow a passenger service to take the Down Fast towards Doncaster from Hull. It is at this point we pass the now closed Hatfield Main Colliery. After 2 passenger services have cleared Stainforth Junction we are run on to the Down Thorpe Marsh towards Thorpe Marsh Junction and finally come to a stand at Heywood Junction where this service was "pathed" for 40 minutes.

All required permissions were granted for the filming of this service as it holds significant historical relevance due to the semaphore signals and various intermediate signal boxes that are now closed and removed after the December 2015 North Lincs Resignalling with control of the route being taken over by York ROC.
