Yet another Oyster question. I've been reading certain posts that say you have to get off trains and touch in at certain stations and I may be misunderstanding.
Am I correct to assume if I start at Waterloo, I touch in and then take the tube. I go to Green Park to change lines, nut I don't need to touch anywhere with the card and then get on another line to South Kensington and then touch out here as I leave the station? So only one touch in and one touch out?
But, if I go to Paddington on the tube to get train to Windsor, I have to touch out even though I am not leaving the station via tube?
