Doesn’t look like the WCML so reckon it must be the SMJ. Feel I ought to know where Roade used to play cricket, but memory is too hazy to recall right now. Anyway that delivery from left of shot was definitely a ‘no ball’ by either the front or rear foot rule - delivery didn’t really start until half-way down the wicket ! I must have watched far too many village games in those days ...
Definitely not the WCML!!
Looks like the 'bridge' under the line is where brook and footpath cross the line, between the two road overbridges in the top left hand corner of the OS plan at https://maps.nls.uk/view/114480620
I wonder if Pianoforte Supplies had a cricket pitch near their works and if that was so was that the location of the match. If so it could have been either line as the LNWR main line would not have been in the deep cutting that far south. The factory was just east of the main line south of the bridge carrying the main road through the village.
