I am thinking that a train travelling north from Louth to Grimsby could not then continue on to Barnetby without reversing at Grimsby. Is this the case. Also trains heading for Grimsby from Louth could not serve or proceed on to Cleethorpes at all. All trains - other than ones coming from Cleethorpes - currently enter the station over the Wellowgate level crossing. In the days of the East Lincolnshire line, was it possible that trains along that line entered Grimsby Town over the Garden Street level crossing? I am not from Grimsby (I was born in Staines) but I lived there for 11-12 years. At the beginning of that period, the East Lincolnshire Line was intact but I was too small to remember much about it, whereas at the time I left, the line had gone and the service was pretty much as it is now.
