A quick look in the papers comes up with just one hit, from the Windsor and Eton Express 03 February 1912.
"Chalvey Station" got a lot more mentions in the papers, but almost all were for the pumping station or the wireless station (a landmark visible from the railway). But there was this from the
South Bucks Standard 05 November 1897, in a report of the Upton-cum-Chalvey parish council:
The proposed Chalvey Station Committee reported:- "Your Committee have considered and agreed upon the draft of a letter to be sent to the Great Western Railway Company, asking that Company's consideration of the desirability of providing a station near the railway bridge in the Chalvey-road, and pointing out the great inconvenience it would be to the residents there."
(Moved and adopted.)
That makes it hard to know whether they were in favour or not, doesn't it? Another report from that year says that the first petition was many years earlier, but that the population of the parish had very much increased since then.
