Clovelly Road - Locomotive Crabbing


Steam_Julie

351 views

I still experiencing problems with my Farish 04 running slowly over the goods yard entry point on Clovelly Road.

 

I have discovered that the problem is that it is crabbing. This means that the loco wheels are moving towards the outside rail. This has the effect of increasing the distance of the loco tyre from the inner rail and thus increasing the electrical resistance.

 

I have proved that my diagnosis is correct, when a stall occurs, I very generally push it towards the inner rail. The loco then starts and runs for a number of circuits without stalling.

 

Eventually the problem returns. The same remedy again works. I think that the solution is to add a check rail on the approach to the point.

Can you move the wheels on the axles to increase the gauge a bit. Other thing would be to do as I have done on several points and fill the frog with solder and then cut it back to give a much narrower gap.

Yes this would be possible, but I wish to keep to the standard back to back dimension. I'm going to install the check rails and then re run the running tests.

This problem of crabbing occurs quite frequently, but most people usually don't attempt to solve it. It often
happens in sidings or extra fiddleyard roads that have been squeezed in.

 

When done I think it will dramatically improve the running and be well worth the effort. The fact that the layout on the main line does not have an reverse curves, or any significant straight track it parts of the problem too.
