Turnout Types
We supply railway turnout assemblies for railway construction, track renewal, station layouts, rail yards, and other railway infrastructure projects. Our supply scope covers different turnout configurations, including single railway turnouts, symmetric turnouts, railway crossovers, double crossovers, railway crossings, and slip switches.
What Is a Railway Turnout?
A railway turnout, also known as a railway switch or railroad switch, allows trains to move from one track to another. It is widely used in railway stations, marshalling yards, main-line railway networks, and industrial track systems.
A typical turnout consists of switch rails, stock rails, a frog, guard rails, and associated components. Different types of railway turnouts are designed for specific track layouts and operating requirements.
When selecting a complete assembled turnout, buyers should consider the rail gauge, rail profile, frog number, applicable standards, and project drawings. Custom railway turnouts can be specified according to project requirements.
Railway Turnout Types
We supply different types of railway turnouts for railway construction, track renewal, stations, marshalling yards, and industrial track systems. Explore the configurations below to identify the right solution for your project.
Single Railway Turnout
Connects one main track to a diverging track. Commonly used on main lines, railway stations, sidings, and industrial tracks.
Symmetric Turnout
Divides a track into two diverging routes arranged symmetrically. Suitable for track layouts requiring balanced branching geometry.
Three-Way Turnout
Connects an approach track to three route options. Used in selected station and railway yard layouts where multiple routes must branch from a limited area.
Railway Crossover
Connects two adjacent tracks so trains can transfer between them. Commonly used on main lines, at stations, and in railway yards.
Double Crossover
Combines two crossover connections to enable train movements between adjacent tracks in both directions. Used where more flexible track routing is required.
Railway Crossing
Allows two railway tracks to intersect at the same level. Used at track intersections where routes cross rather than simply diverge.
Single Slip Switch
Combines a track crossing with one connecting route between intersecting tracks. Suitable for compact station layouts where space is limited.
Double Slip Switch
Combines a track crossing with connecting routes in both directions. Used in complex station throats and railway yards where multiple movements must fit within limited space.
Compare Railway Turnout Types
Different railway turnout configurations serve different track layouts. The right choice depends on the required route connections, available track space, rail profile, and project design.
| Turnout Type | Track Configuration | Typical Application |
|---|---|---|
| Single Railway Turnout | One track branches into two routes | Railway lines, stations, and sidings |
| Symmetric Turnout | Two symmetrically arranged diverging routes | Specified symmetric track layouts |
| Railway Crossover | Connects two adjacent tracks | Stations and multi-track railway lines |
| Double Crossover | Provides crossover connections in both directions | Complex multi-track layouts |
| Three-Way Turnout | One approach track connects to three route options | Selected railway yards and stations |
| Single Slip Switch | Track crossing with one connecting route | Space-constrained track layouts |
| Double Slip Switch | Track crossing with connecting routes in both directions | Complex station layouts |
| Railway Crossing | Two tracks intersect at the same level | Track intersections |
How to Choose the Right Type
For a simple diverging route: Consider a Single Railway Turnout.
For transferring trains between adjacent tracks: Consider a Railway Crossover.
For multiple route options within a limited area: Evaluate a Three-Way Turnout or a slip switch, depending on the track layout.
For intersecting tracks without a route connection: Consider a Railway Crossing.
The final configuration should be confirmed against the project drawings, applicable railway standards, rail profile, track gauge, and operating requirements.
