How the Gilmour Rain Train Traveling Sprinkler Works
The Gilmour Rain Train Traveling Sprinkler is a self-propelled lawn sprinkler that uses water pressure to do two jobs at once: spray water across your lawn and slowly move itself along the path of your garden hose.
Instead of staying in one place like a standard sprinkler, the Rain Train travels forward while watering, making it a practical choice for large lawns, long yards, gardens, and open areas.
The Basic Idea
To use a traveling sprinkler, you lay your garden hose out on the ground in the path you want the sprinkler to follow. Once the hose is in place, you connect the Rain Train, turn on the water, and the sprinkler begins to move along that hose path while spraying water on both sides.
The hose acts like a track. The sprinkler does not randomly drive around the yard. It follows the route you create with the hose.
How It Moves
Inside the Gilmour Rain Train is a water-driven drive system. As water enters the sprinkler, it powers an internal turbine or gear mechanism. That motion is transferred to the wheels, which causes the sprinkler to move forward.
In simple terms, the water pressure acts like the engine. No batteries or electricity are needed. As long as there is enough water pressure and flow, the sprinkler can spray and travel at the same time.
How It Follows the Hose
The Rain Train is designed to track along the garden hose underneath it. Because of this, the shape of the hose determines the path of the sprinkler. You can lay the hose in a straight line, a gentle curve, or around part of a lawn or garden bed.
This gives you much more control than a stationary sprinkler. Instead of moving a sprinkler by hand every few minutes, you can set the hose route once and let the sprinkler travel on its own.
How the Sprinkler Head Works
On top of the unit is the impact-style sprinkler head. Water is forced through the spray arms, creating the familiar sweeping sprinkler pattern that throws water out in arcs over the lawn.
This rotating sprinkler head distributes water across a broad area while the body of the Rain Train slowly moves forward. That combination is what helps it water a long section of lawn more evenly than a sprinkler that stays in one place.
Why It Waters Evenly
A regular sprinkler only waters the area around it until you move it. A traveling sprinkler covers more ground because it keeps moving while it sprays. This helps reduce dry spots and saves time on larger lawns.
The Gilmour Rain Train is especially useful for:
- Large lawns
- Long side yards
- Garden areas
- Pasture edges
- Open spaces where a standard sprinkler does not reach easily
Travel Speed Settings
Most Rain Train traveling sprinklers have multiple travel settings, typically including:
- High speed
- Low speed
- Neutral
Low Speed
On low speed, the sprinkler moves more slowly. Because it spends more time over each section of lawn, it applies more water to that area.
High Speed
On high speed, the sprinkler moves faster. This means it applies less water to each section of lawn.
Neutral
On neutral, the sprinkler typically stays in one place and works like a stationary sprinkler instead of traveling. This is useful when you want to water one area without moving the unit.
Spray Coverage Adjustment
The Gilmour Rain Train also lets you adjust the spray pattern. Depending on the model and settings, you can control how widely the water is thrown, which helps match the sprinkler to the size and shape of the area you want to water.
By adjusting both the travel speed and the spray width, you can control how much water the lawn receives.
Automatic Shutoff Feature
One of the most useful features of a traveling sprinkler is the automatic shutoff. At the end of the hose path, you place a stop ramp or shutoff device on the hose. When the Rain Train reaches that point, it stops traveling and typically shuts off the water flow depending on the model and setup.
This keeps the sprinkler from continuing past the end of the route and makes watering more automatic.
How to Set Up a Rain Train Sprinkler
- Lay the garden hose out in the path you want the sprinkler to follow.
- Keep the hose path as smooth as possible, with no sharp kinks or tight bends.
- Attach the Gilmour Rain Train to the hose.
- Select the travel speed.
- Adjust the spray pattern if needed.
- Place the shutoff ramp or stop at the end of the hose path.
- Turn on the water and let the sprinkler begin watering and traveling.
What Affects Performance
Traveling sprinklers work best when a few basic conditions are met.
Water Pressure
The sprinkler needs enough water pressure to both operate the sprinkler head and power the drive mechanism. If pressure is too low, it may spray weakly, move too slowly, or fail to travel correctly.
Hose Layout
A smooth hose layout matters. Sharp bends, tight twists, or kinks can interfere with the sprinkler's ability to follow the path properly.
Ground Conditions
The Rain Train works best on relatively even ground. Very rough terrain, steep slopes, deep ruts, or obstacles may affect travel.
Clean Internal Parts
Dirt, mineral buildup, or worn internal gears can reduce performance. Keeping the sprinkler clean and storing it properly can help it last longer and work more consistently.
Common Problems
If the Rain Train is not working correctly, the most common causes include:
- Low water pressure
- Clogged sprinkler head
- Debris in the drive mechanism
- Sharp hose bends or kinks
- Wheel slippage
- Worn gears or internal parts
If the sprinkler sprays but does not move, the problem is often in the drive system or water pressure. If it moves but does not water well, the issue may be with the sprinkler head, spray adjustment, or overall flow.
Why Homeowners Like the Rain Train
The Gilmour Rain Train Traveling Sprinkler remains popular because it is simple, mechanical, easy to understand, and practical for watering larger spaces without constant attention.
It is a good fit for homeowners who want:
- Less time spent moving sprinklers by hand
- Better coverage on larger lawns
- A simple mechanical sprinkler with no electronics
- A classic traveling sprinkler design that still works well today
In Simple Terms
The Gilmour Rain Train Traveling Sprinkler works by using water pressure to power both the sprinkler head and the internal drive system, allowing it to follow your hose path and water a long section of lawn automatically.
