Hello fellow railroaders!
I have been wondering if any users have experimented with alternative to avoid wheel slippage on locos.
My observation is that the majority of dirt on the outer rail is due to the rubber tire being worn out and leaving a black smudge behind.
So is there any (more last longing and maybe different material) tires on the market. Why e.g. is there no silicone tires?
Or have users experimented in replacing the wheels with normal wheels and adding weight to the locomotive to avoid wheel slippage (I believe this is common practise on large scale locos)?
I heard about the bull frog snot – any thought on that one?

Bullfrog Snot is a silicon compound, I believe. I tried it on a couple of my Z scale locos and wasn't impressed. |

years ago I've tried to produce some adhesive tyres commercially but gave up the idea when I was told the price of each.
Rubber although suitable in some ways isn't ideal for this application. any oil or grime will deteriorate the rubber compound very quickly.
I don't think anybody else is producing tyres withstanding oil or grime.
regards,.

Hmm. I wonder if Nitrile or Viton would work better? They are common O-ring material that resist most oils and are used in hydraulic cylinders.
We would need to get some, freeze it and machine some tires to try out. If it is successful, then it is worth the cost of molds.
Hmm. Perhaps some large diameter, tiny cross section o-rings are already available? I will ask my local seal vendor, I have a project at work requiring o-rings... |
