- 1). Dig a trench, if working outside, about 2 to 3 inches deep. The trench gives stability to your ballast and allows for water drainage.
- 2). Fill the trench with ballast to the level of the trench. Use a brick or mallet to tap the rocks to make the ballast level and secure. The jagged edges of the rocks will lock together.
- 3). Place the track onto the ballast and level. This is time-consuming, slow work. Do not try to rush it. Making sure that each section of track is securely in place and level will result in a smoother running train line.
- 4). Add extra ballast material around in between the track. Tap the ballast to make sure it is secure.
