If you visit Southern UK - Sussex area, you can enjoy visiting Bluebell Railway. Bluebell is a masterpiece of well preserved more than hundred year old railway. It spans across distance of about 15 km. You can visit three railway stations, travel in old carriage, even eat lunch in Pullman car. What I admire most is preservation of every small detail - as it was long, long time ago. And Bluebell still grows - there are plans to extend railway as well as new steam engines are being reconstructed.
