Ah yes, I hadn't checked, just made the note while I was here. It looks like CoMaps wasn't routing along this path because it couldn't find any connection between Lower Brook Street and Teignmouth station. As often happens when footpaths/pavements are forgotten about and only included as part of roads. I've added a pavement going between the two and some crossing to make this work as best I can. It's not perfect, but I think it makes sense and should fix routing issue.
