Walking in the Shiplake locality this morning, I was delighted to come across the supports of the "lifted" track of the Henley branch where it crosses the Thames near Wargrave. Substantial remains to find on such a short branch.
(And just south of Shiplake Station there are less-impressive brick supports where the Thames Path goes under the railway after leaving the river.)
I guess that it was Regatta traffic that justified the doubling of the track - seems quite an investment for just a couple of weeks a year. The line was singled in 1961.
