Diesel 10 is the bad guy from Thomas the train and the favorite of my son Thomas. We call him Thomas 10. I used some of the Thomas the Train costume ideas on the website to make my own homemade Thomas the Train’s Diesel 10 Halloween costume idea.

I started with a Christmas tree box to get the right rectangular shape cutting out a square that he could easily fit thru. I primed the box with 2 cans of primer spray paint, then painted it a wicker yellow with touches of gold spray paint. I made the windows and stripes from extra cardboard cut with an exacto knife and spray painted them. They were attached with a hot glue gun at first, but they kept falling off. I had the best luck with Gorilla glue (a little goes a long way).

The face is made from model magic on a thin cut piece of cardboard (cereal box). After letting it dry for a day, I painted it with grey acrylic paint and black acrylic paint for the eyebrows. Extra large googly eyes capped it off. I used contact cement to apply the cardboard back of the model magic to the Christmas tree box.

The red stripe and black buffers are just tape I had lying around the house.

My husband helped by cutting out a form for the wheelbase. We used foam discs from the floral department painted black for the wheels. These were also attached using gorilla glue.

For the straps we bolted on black elastic strips for sewing. They were a little long as they stretched so we had to crisscross them. The most important part of this homemade Thomas the Train’s Diesel 10 Halloween costume idea is definitely the “pinchy” for any true Diesel 10 lover. We went with a pooper scooper (brand new and clean!). Ours was black but you could spray paint it if you wanted.

Top off your conductor in the train with a Conductor’s hat and a red bandanna.

Time spent: 3 days
$$ spent: $50 (mostly the spray paint)

The costume was a little heavy and he needed help at times. If you have a little train lover, you may want to use the wagon idea with it.
