One that always fascinates me and I have never found any information about is on the Low Level line heading towards Lanark out of Glasgow Central. It is early on, (Before your bum had gone numb from the seats on the "Blue Trains". They were hard if you were going all the way out to Lanark) and still in the underground section but on the right, just visible in the light from the carriage windows there is a large area with a row of ornate columns in front of it. I don't know if it is a long closed station or something else but it is a strange thing to see in what is basically a railway tunnel and a very ornate construction to be hidden, unused, underground. I would love to know its history.
