Spoilt for choice again.

So soon after the Derwentwater trip, we found ourselves in Keswick again and on the line again. This time we tackled it from t'other end (Keswick).
Since the lass's ticker problem we haven't made the full length, but thoroughly enjoy the bits we do get to see.
I had to fetch in the arbitrator again as I had too wide a choice.

Amongst the other possibles were ...
1. An answer to my perpetual question. Where
did the railway line run? Coz sure as The Lord made Lahl Taties, it wasn't up here.
2. A rectangular concrete tubular view to contrast with the link, above.
