Atlas HO Scale Switch Machine Remote Right
Brand: Atlas. Features include screw-on remote switch machines that quickly convert standard switches to remote control. The unit provides a way to wire the switch to be thrown from your control panel, enhancing layout automation. It includes metal machined screws and hex nuts for secure installation.
HO Code 100 Remote Left-Hand Switch Machine
Brand: Atlas. This remote left-hand switch machine is designed for HO scale layouts, suitable for use with your model railroad. It emphasizes compatibility with standard HO track and remote operation, enabling convenient turnout control from a central panel or dispatch area.
Atlas Remote Switch Machine Left for Code 83 & True-Track
Brand: Atlas. This small-footprint machine is designed to minimize table space while delivering reliable turnout control. It also notes compatibility with True-Track switches, making it a flexible option for modern HO setups where space is at a premium.
Atlas Remote Switch Machine Right for Code 83 & True-Track
Brand: Atlas. Similar to the left-handed version, this compact device fits Code 83 and True-Track switches, offering reliable remote operation with a small footprint ideal for layouts with constrained space or dense trackwork.
Walthers Layout Control System — Horizontal Mount
Brand: Walthers. A fully assembled, servo-based unit with a quick one-second throw speed. It includes an integrated DCC accessory decoder and two built-in 5A switches to power turnout frogs, signals, and track blocks, delivering a comprehensive layout control solution with higher automation potential.
HO Code 100 Manual Right-Hand Switch Machine
Brand: Atlas. Manual right-hand switch machine option for HO code 100 track. It provides a straightforward approach for users who prefer manual control over turnout operation, suitable for traditional layouts or where electronics are minimized.
Buying Guide: Key Purchase Considerations
Turnout control type: Remote, manual, or servo-based systems each offer different levels of automation, reliability, and integration with DCC layouts. Remote and servo-based options generally provide quicker, more consistent throws, while manual machines are simpler and lower in electronics.
Code compatibility and track family: Verify that the switch machine supports your HO code (Code 83 or Code 100) and your preferred switch type (including True-Track gear where applicable). Some models specifically advertise True-Track compatibility for smoother operation on modern turnouts.
Footprint and layout space: Compact machines save table space and are ideal for dense or compact layouts. If space is a critical factor, focus on the lightweight, small-footprint options from Atlas that advertise limited table occupancy.
Power and wiring: Consider how the unit powers and wires into your control system. Some products integrate with DCC accessories decoders; others require separate wiring for control panels and turnout frogs. Ensure compatibility with your existing layout’s power supply and control scheme.
Reliability and speed: Look for a fast throw (often around a second for servo-based units) and robust mechanical construction. Machines with metal components and secure installation hardware tend to resist wear and provide longer service life on busy layouts.
Ease of installation: Some machines come fully assembled and ready to mount, while others require more hands-on wiring or panel integration. Manuals and support resources can help ensure a smooth setup and reduce troubleshooting time.
Future expansion: If you plan to automate more turnouts, consider machines that support easy expansion, integration with decoders, and compatibility with current or planned layout control systems.
