Product Information

Full details

This guide is for model railroad enthusiasts using OO/HO scale track. The PECO SL-88 is a right-hand turnout designed for large radius curves, offering smooth transitions and reliable operation for your train layouts. A potential consideration is its specific code 100 standard, which may influence compatibility with very fine-scale or older track systems. Key features include its streamline design, insulfrog electrical configuration, and precise geometry for realistic operation.

FAQs

What scale is the PECO SL-88 turnout designed for?

The PECO SL-88 turnout is designed for OO and HO scale model railways.

Is this a left-hand or right-hand turnout?

This is a right-hand turnout, meaning it guides trains to the right when diverging from the main line.

What does 'Insulfrog' mean?

Insulfrog means that the frog (the V-shaped section where the rails cross) is made of insulating material. This helps prevent short circuits on the diverging route when it's not powered.

Can I use this with Digital Command Control (DCC)?

Yes, you can use it with DCC. For optimal performance, especially with sound-equipped locomotives, it is recommended to wire the frog to be continuously powered using a frog juction box or a similar accessory.

What is Code 100 rail?

Code 100 refers to the height of the rail. Code 100 rail is a common standard in OO/HO modeling, measuring approximately 0.100 inches high.

How do I connect it to other track pieces?

The SL-88 connects to other Code 100 track sections using standard metal rail joiners, which slide onto the ends of the rails.

What is the radius of this turnout?

The SL-88 is a large radius turnout, designed for expansive curves. PECO specifies it for their large radius curves (e.g., R2). Consult PECO's track planning guides for exact radii in various configurations.

Troubleshooting

Train derails on the turnout.

Check that the turnout is securely fastened to the baseboard and is not warped. Ensure the point blades are fully thrown and aligned with the correct rail. Clean the running rails and check for any debris or fluff interfering with the wheels or track.

Electrical short circuit.

Verify that the insulfrog frog area is clear of conductive debris. Ensure no wires are shorting to the track. If powering the frog, double-check the wiring connections for correctness and polarity.

Point blades do not move freely.

Inspect the point mechanism for obstructions. Gently clean any dirt or debris from the moving parts. Apply a minimal amount of appropriate model lubricant to the pivot points if necessary. Ensure the manual or electrical actuation mechanism is properly aligned.

Locomotive stalls when crossing the turnout.

If using DC, ensure the points are correctly set for the direction of travel and the track is clean. If using DCC, it is highly recommended to wire the frog for continuous power to ensure a constant electrical feed to the locomotive's pickup shoes.

Pros and Cons

Pros

  • Facilitates the creation of large, flowing curves for realistic model railway designs.
  • Streamline profile offers a clean, integrated look with other PECO track components.
  • Insulfrog design simplifies wiring for basic DC operation and reduces the risk of shorts.
  • Code 100 rail height offers broad compatibility with most OO/HO scale rolling stock.
  • Robust construction ensures longevity and dependable performance.

Cons

  • Primarily designed for large radius curves, may not be suitable for tight-space layouts.
  • Code 100 rail height can be slightly thicker than finer scales (e.g., Code 75 or 83), potentially noticeable on close inspection.
  • Requires specific wiring for powered frog operation if desired, adding complexity for DCC users needing continuous power.
  • Being a right-hand turnout, it requires a corresponding left-hand turnout (SL-89) for full double-track or crossing layouts.

Setup, Compatibility & Care

Setup: The PECO SL-88 is designed to be laid on a suitable baseboard or sub-roadbed, typically ballasted to secure it in place. It connects to other Code 100 track sections using standard rail joiners. Ensure the turnout is laid on a flat, stable surface to prevent warping. For electrical conductivity, ensure rail joiners are firmly seated. If powering the frog (recommended for DCC), additional wiring will be needed to connect to a suitable power source, often controlled by a point motor or an accessory decoder.

Compatibility: This turnout uses Code 100 rail, which is compatible with most standard OO and HO scale rolling stock. It integrates seamlessly with other PECO Streamline Code 100 track, including straights, other turnouts, and curved sections. While compatible with many brands of Code 100 track, minor variations may exist. It is less compatible with finer scale track systems like Code 75 or Code 83 due to the rail height difference.

Care: Keep the turnout free from dust, debris, and especially fluff, which can accumulate and interfere with the point movement or cause derailments. Periodically clean the running rails with a track cleaning eraser or fluid. Ensure the moving point blades are free to operate; a tiny drop of specialized model lubricant may be applied sparingly to the pivot points if needed, but avoid over-lubrication which can attract dirt.
