The Danks Dilemma
Just how far did it go?
The trouble with getting new source material is that suddenly details disagree and what once seemed certain can no longer be considered fact.
Take the Danks Branch near Balls Hill. The 1902 series OS map was quite clear that the branch terminated at Danksbranch Wharf, immediately beside the Tame Valley Canal. This seemed a bit odd as it would have been so simple to cut a route through on the level.

I decided to test Richard Chester-Browne's "The Other 60 Miles" by reviewing a section I know well and there at there end of the Danks Branch the hand drawn map suggest not only a junction but also a short arm beyond the Tame Valley Canal, presumably from before the Tame Valley was built.

Which map is accurate? I have absolutey no idea. Richard's work was drawn from the OS Six Inch series published 1880, so the link may have been lost in the course of the intervening 22 years, but this seems unlikely. For my money I would opt for the primary source every time, and suggest that the rendition by Marcus Boudier may be slightly inaccurate.
In truth, no one knows, there is no evidence of the ground and no one really cares.
If any of you guys have a third source of data to support either option please let me know and I will add an update, giving you due credit of course
