Choo choo trains are a big deal at our house. For starters, we have the honor of viewing train tracks from our living room window. We get to hear and see the red MetroRail train come by our house multiple times a day. The kids love it and I love that they love it! Needless to say, both kids adore trains and this cardbaord train costume is a big hit!

Last year, we made a Chrsitmas themed DIY cardboard box train for JW Marriott Light up the Nigh holiday kick off event. This year, I’m super excited to host the train craft portion of the event again! I want to get the most use out of our DIY train costume, so I’m making it for Halloween and then I’ll give it a little Christmas spunk up for the Light Up the Night holiday event that happens at the JW Hill Country San Antonio Resort on Nov. 18th!

How to make a DIY train costume
Step 1- Cut the diaper box
Use the XACTO knife to cut a square in the bottom of the diaper box. It doesn’t have to be perfect, just make sure that your kiddo can fit inside of the box. Be sure to cut the flaps off of the top of the box.

Step 2- Cut circles
To male the train wheels, cut 6 circles and 3 rectangular trim pieces with the XACTO knife. I used a kitchen bowl to trace the circles. The trick is to make sure that 3 wheels will fit on each side of the train. I did not use a trim peice on the front of the train since the plate covered the entire front.

Step 3- Paint the wheels
I used grey and black paint to make the train wheels.
Step 4- Assemble the train
Use a hot glue gun to assemble the train. Last year, I attached the train wheels before spraying the entire train black. This year, I first spray painted the wheels silver, and then hand painted the black spokes with acrylic paint. After everything was dry, I attached the wheels under the trim pieces with a hot glue gun.

Step 5- Add accessories
I used turquoise washi tape to make two stripes on the cardboard box train. Next, I added the numbers. This was the most crucial part of the train for Maxwell. He loves numbers, and really wanted a three and a four. I cut the numbers out of grey foam and hot glued them to the side of the train.
Step 6- Add straps
Last but not least, you will need straps to hold the train on the kiddos shoulders. I used black felt that I had on hand to make the straps this year. Last year, I cut the handles off of an old reusable bag, and that worked great too. I used a hot glue gun to attach the straps to the inside of the train.

Step 7- Dress the conductor
Add a red bandana and a conductor style hat and bam… you’ve got yourself a conductor and a train! Chuga chuga choo choo! It’s fair to note, that I do not let Maxwell play on the train tracks. He was actually very nervous about this photo shoot since I always make such a big deal about not playing anywhere near the tracks.

The big dilemma is who is wearing the cardboard box train for Halloween… Mila or Maxwell? It fits them both pretty well! I feel like it will be a game time decision. There are a few DIY costumes in the works, so the final decision will likely be made on the Halloween day!

If you live in Texas, here are a few more deets about the annual Light Up the Night event at the JW Marriot San Antonio. This will be our 3rd year attending, and we love it! Santa and Mrs. Claus flip on the switch to the holiday light show, and in my opinion, it’s the very best place to get Santa pictures! (Check out my list of 18 fun, free things to do at the JW Marriot San Antonio.) There’s hot chocolate galore, a giant sleigh, and the kids can make a box train with me and then lead Santa to flip the switch to turn on the holiday cheer! It’s the cutest. Guests of the resort and locals are welcome. I’d love to meet you and your kiddos!
but how do you attach the straps? 🙂 trying to find a good tutorial but not sure how/where to attach the straps so they can wear
Good question! I attached the straps with a hot glue gun to the inside of the train. Basically on either side of the hole you cut out for the kiddo to stand inside the train car!
