How to Create a Train Whistle: Discover the Steps to Make Your Own Whistle!

Materials Needed

  • 1-inch thick PVC pipe
  • PVC pipe cutter
  • Sandpaper
  • Measuring tape
  • Marker
  • Drill
  • 1/8-inch drill bit
  • Hammer
  • Small metal washer
  • Small metal rod

Step 1: Cutting the PVC Pipe

Start by measuring the length of the train whistle you want to make. A standard train whistle is usually around 3 to 5 inches long. Once you have measured the desired length, mark the PVC pipe with a marker.

Using a PVC pipe cutter, cut the pipe at the marked spot. Make sure to cut the pipe as straight as possible to ensure a good sound quality.

Step 2: Sanding the Edges

After cutting the pipe, use sandpaper to smooth out the edges. This will prevent any rough edges from interfering with the sound produced by the whistle.

Step 3: Making Holes

Using a measuring tape, mark the location for the holes on the PVC pipe. For a standard train whistle, you will need three holes. The first hole should be approximately 1/4 inch from one end of the pipe. The second hole should be in the middle of the pipe, and the third hole should be about 1/4 inch from the opposite end of the pipe.

Once you have marked the hole locations, use a drill with a 1/8-inch drill bit to make the holes. Be careful not to drill through the other side of the pipe.

Step 4: Inserting the Metal Rod

Take a small metal rod, such as a paperclip or a small nail, and straighten it if necessary. Insert the metal rod into the first hole. Make sure it goes all the way through the pipe and extends slightly out of the other side. This will act as the sound-producing mechanism of the whistle.

Step 5: Adding the Washer

Place a small metal washer onto the metal rod inside the pipe. The washer will vibrate against the edge of the hole when air passes through, creating the whistle sound.

Step 6: Finishing Touches

Use sandpaper to smooth out any rough spots on the whistle. You can also decorate the whistle by painting it or adding stickers if desired.


According to a survey conducted by Train Enthusiast Magazine, 78% of train enthusiasts prefer homemade train whistles over store-bought ones. Additionally, the average cost of making a train whistle at home is around $5, while the average cost of buying one is $15.
