Didcot railway is a lovely museum/tourist attraction in Oxfordshire. It is home to over 200 years of railway heritage. There are two stations, a transfer shed, a locomotive turntable, the engine shed, air raid shelter, a museum, gift shop, and refreshment room. The refreshment room has vegan options, including main and dessert. The gift shop is great as well.
They offer train rides for free, or included in the entry fee, depending on how you want to see it. Enjoy the pictures!
