A heritage rail example. Pre-covid when we ran evening trains a couple of times a month, you could get a superb soundscape in Medstead and Four Marks Signal Box. On a still night, above the ticking of the clock, and an owl in the woods, you'd hear a down train leave Alton, 4 miles north, then get two bells on the token machine to indicate train entering section. Similarly, if lucky, maybe with a slight southerly breeze, you could just hear a train leave Alresford, six miles south, and a little while later get the train offered on by the signalman at Ropley, knowing it would likely be around 25 minutes before it reached you. Being at the top of the hill and in a relatively quiet bit of countryside certainly helped. Hopefully the experience will be back later this year.
