Can I be a little controversial and suggest that as well as all this angst over an unused and inaccessible station closing might be well-meaning, there's a small possibilty it's counter-productive?
There have been people suggesting questioning it with their MPs, MSPs or the Scottish Parliament directly, despite living nowhere near the place. It's highly likely that whoever you write to won't give a stuff, but there's also a small chance you write to someone who had no idea an under-used station was being closed but makes them wonder which other stations there are with no, or few, passengers and can lobby for them to be closed as a waste of money.
Be careful what you wish for. Trains will not stop there again come December. Drawing attention to anomalies on the railways is rarely a good thing - you're all doing the physical equivalent of pointing out a fare anomaly or a good point to split fares.
It's sad it's going, but it's already gone. Let it go with a little dignity rather than trying to prove some theoretical point.
