One idea could be to plan a weekend trip to a scenic railway for a romantic getaway. You could book a quaint bed and breakfast nearby and spend the weekend exploring the railway and the surrounding area. Another idea could be to purchase a vintage train model or train photography for her to display in your home. If she enjoys reading, you could also get her a copy of a popular train related book, such as "The Great Railway Bazaar" by Paul Theroux. Alternatively, you could plan a date night where you watch a train themed movie or documentary and make her a train inspired meal.
Or you can get her a star map with the date of your anniversary.
