What is the most circuitous route between 2 stations on the same line? I nominate Ulverston to Kirkby in Furness, 18m 71 ch via Barrow but only about 4.5 miles as the crow flies. (Shorter via the non-passenger loop but the Rail Miles mileage engine said it was unable to calculate the distance!) I put this to good use on 3 sunny Saturdays in September 2018, when I booked to Kirkby in Furness and walked back over the fells to Ulverston on 2 days, and on the third walked the other way, including the interesting remains of the old 3-foot gauge slate tramway from the quarries down to Kirkby.
