Hello Christine,
Thank you for visiting us here at the Disney Parks Moms Panel. I hope you are all having a train-tastic day.
My boy loves to chug-chug-chug his toy trains and cars to make perfect lines all over the house. So when we arrive at Disneyland Park and see the famous Disneyland Railroad stopped at the Main Street, U.S.A. station, he is in awe. While there is not a specific tour of the Disneyland Railroad Train, the conductor is always onboard for questions from Guests. Your boys (of all ages) can enjoy a ride on the Disneyland Railroad as it makes stops at New Orleans Square, Tomorrowland, Mickey’s Toontown and Main Street, U.S.A., it’s a perfect way to relax and see a lot of Disneyland Park from a unique view.
Here is the link to the Disneyland Railroad that I think your boys will enjoy.
I hope this brought some magic to your day. Please let me know if I can assist you any further before your visit.
Have fun on your adventure at The Happiest Place on Earth!
~ Lynette
