One idea could be to purchase a limited edition or rare model train piece to add to his collection. You could also consider getting him a book or magazine related to model trains or even signing him up for a membership to a local model train club. Additionally, you could plan a romantic train ride together on a scenic railway, or surprise him with a weekend getaway to a train-themed destination, such as a train museum or historical train station.
Or you can get him a star map with the date of your anniversary.
