premise: Joan Croft Halt railway station was a small halt on the East Coast Main Line (ECML) situated by a level crossing at Joan Croft Junction in South Yorkshire, England. The junction gives access from the ECML to the Skellow line of the West Riding and Grimsby Railway and eventually to Hull, Immingham and Grimsby Docks.
hypothesis: Travelers on the East Coast Main Line stop at Joan Croft Halt railway station some distance away from the Joan Croft junction which gives access to the Skellow line of the West Riding and Grimsby Railway
reason: From context, I mean from the word "a small halt" it seems travelers experience stopovers at different spots while commuting by train and the railway station on the East Coast Main Line seems to be the perfect spot.
