Elizabeth line, Slough to Taplow.
Elizabeth Line: Bond Street 9.26, Paddington 9.30, Ealing Broadway 9.41, Slough 10.01. If there is a problem with the Elizabeth Line there is a 9.30 train from Paddington that arrives at Slough at 10.01.
The Pineapple, when you reach the Dorney wetlands the B3206 crosses the path Turn R , North, towards the M4 and you willl find the Pineapple on the left hand side of the road. I have marked it on the map with a cross.
The advantage of the Elizabeth line is that it is considered part of the underground network and your freedom pass is valid all along the line. However if there is a problem there is a “steam “ train from Paddington to Slough
I cannot find the walk details on line so I will take photos and include them in the email.
