The Secret Railway (Female Controller Reader)

After the death of Sir Charles T. Hat, some of his engines have managed to be saved and have been put on a secret railway that is completely hidden from the rest of the world, and has all the supplies it needs. (Y/N) is the controller of the railway, and she is very kind to all the engines, and she manages to find endless supplies of fuel to run the railway. Over the years, new engines come who have been either forgotten, or sent for scrap. (In loving memory of Reverend Awdry and Michael Angelis)
