Troubleshooting Problems a Guide

 

Problems?  here are some Troubleshooting tips.

When you’re starting with a model railway, you might run into some common issues. Here’s a list of problems you might encounter, along with solutions to help you troubleshoot and fix them:

1. Train Stalls or Stops Intermittently

Problem: Your train stalls or suddenly stops while running, even though there’s no apparent obstruction. Solution:

  • Check the track: Make sure there are no dirt, debris, or oxidation on the rails. Clean the track with a track cleaning tool or a soft cloth.
  • Inspect the wheels: Ensure the wheels of the train or rolling stock are clean and not clogged with dirt. A glass fibre pencil is ideal for cleaning loco wheels
  • Check the connections: Ensure that the track sections are properly joined and that there’s good electrical contact.
  • Test the power supply: Make sure the transformer or DCC controller is working properly and providing adequate voltage. its useful to have a simple Multi-meter

2. Poor Electrical Contact

Problem: The train runs sluggishly or hesitates when crossing track joins. Solution:

  • Track alignment: Ensure track pieces are aligned properly and there’s no gap where pieces meet.
  • Clean the track: Dirt or oxidation on the track can prevent good electrical contact, so clean the rails using a track cleaning tool and contact spray.
  • Check the rail joiners: If the rail joiners are loose or corroded, replace or tighten them for a better electrical connection.

3. Track is Misaligned or Warped

Problem: Sections of track are misaligned, causing trains to derail or struggle to stay on the track. Solution:

  • Check track placement: Make sure the track is laying flat and that all joints are secured properly.
  • Use track pins or adhesive: For permanent setups, use track pins or adhesive to keep the track in place.
  • Inspect the baseboard: Make sure the surface underneath the track is level. Use a spirit level to check for uneven spots.
  • Correct any warp: If the track is warped, gently re-bend it or replace sections that cannot be corrected.

4. Trains Derail

Problem: Trains fall off the track or derail at curves or switches. Solution:

  • Check the track gauge: Make sure the track is of the correct gauge and that there are no gaps in the rails. The wheels on the trains should fit the track properly.
  • Inspect the switch points: If the train derails at a turnout, make sure the switch points are properly aligned.
  • Test the radius: Ensure that your curves aren’t too tight for the type of train you’re running. Larger trains need larger curves.
  • Check the rolling stock: Ensure wheels and axles are in good condition and properly aligned.

5. Electrical Shorts

Problem: The system shuts down or trips the circuit breaker when running the train. Solution:

  • Check for track contact: Ensure no sections of the track are touching each other inappropriately, especially where there’s a power feed.
  • Inspect wiring: If using DCC, ensure the wiring is correctly connected to avoid shorts between wires.
  • Look for debris: Small pieces of metal or wire that have fallen onto the track can cause a short.

6. Unstable or Poorly Positioned Scenery

Problem: Scenery elements like trees, buildings, or roads fall over or don’t stay in place. Solution:

  • Use strong adhesive: For heavier pieces, use a strong glue or hot glue gun that’s specifically designed for model scenery.
  • Secure lightweight items: Use foam, plaster, or other lightweight materials to create stable bases for structures.
  • Ensure proper drying time: Allow glue to set before moving or placing anything on top of the scenery.

7. Problems with DCC Control (if applicable)

Problem: The DCC system isn’t controlling trains or accessories correctly. Solution:

  • Check wiring: Verify that all wires are correctly connected to the track and power supply.
  • Programming the decoder: Make sure your DCC decoders are properly programmed to the right address for each locomotive.
  • Signal interference: Make sure there is no interference on the track or power supply. Keep wires tidy and ensure they’re securely connected.

8. Unwanted Noises or Vibrations

Problem: Your train makes loud, grinding, or rattling noises while running. Solution:

  • Check wheels and tracks: Clean the wheels of the train and the track to ensure smooth operation.
  • Lubricate the train: Apply a small amount of oil to the moving parts of your train, such as the wheels or motor, to reduce friction and noise.
  • Inspect rolling stock: Ensure all carriages are running smoothly on the track and are not dragging.

9. Train Runs Too Fast or Too Slow

Problem: The train runs too fast, even on low power settings, or is very sluggish. Solution:

  • Check the power supply: If using a DC controller, check the power supply and the settings to ensure the right voltage is reaching the train.
  • Inspect the motor: For slower trains, the motor may need servicing, cleaning, or lubricating to restore smooth performance.
  • Consider adding resistors: If the train is running too fast on low power, you may need to adjust the settings or use a resistor to reduce the speed.

10. Landscape Materials Not Sticking

Problem: Grass, trees, or other landscape elements don’t adhere well to the scenery base. Solution:

  • Use scenic glue: Use a dedicated scenic glue or white PVA glue, diluted with water, to stick materials securely.
  • Static grass applicator: If using static grass, a static grass applicator can help stand the fibers up more effectively.
  • Layering: Apply several layers of grass or foliage to help fill in gaps and achieve a more natural look.

With these solutions, you should be able to troubleshoot many of the common issues in model railroading. Remember, patience is key, and with time and practice, you’ll get the hang of things!
