HO 3 Aspect Colour Signal with Call On Target provides flexible route control and realistic operational signalling for HO scale model railways.

Featuring:

• 3-Aspect Colour Light Signal: Displays red, yellow, and green aspects for realistic block section control and route management.
• Call-On Target Indicator: Enables permissive movements into occupied sections for platform sharing or yard operations.
• HO Scale Compatibility: Designed for HO scale (1:87) layouts with modern or transitional signalling schemes.
• Operational Realism: Supports prototypical train sequencing, braking distances, and controlled entry into complex track areas.

Model Dimensions (Approximate):

• Scale: HO (1:87)
• Height: Varies depending on prototype style

Technical Specifications:

• Accessory Category: Railway Signal
• Signal Type: 3 Aspect Colour Light Signal with Call-On Function
• Scale: HO (1:87)

Perfect for: HO scale railway modellers building busy mainlines, station approaches, and yards requiring realistic multi-train operations.

Why this accessory matters

Three-aspect signalling forms the backbone of modern railway control systems, allowing trains to be safely spaced using advance warning indications. The addition of a call-on function introduces further operational depth, enabling controlled entry into occupied blocks where required.

This combination makes it possible to replicate authentic railway working practices such as station platform sharing and regulated yard access.

How to use it

Install the signal adjacent to the relevant track section and connect it to your signalling control system or decoder setup. Configure the aspect logic and call-on function according to your layout’s operating rules before use.

This is a model railway accessory. Electrical installation is required. It is not a toy.
