    Hi Craig Bull frog snot works very well, you just have to be careful not to over do it. The way I use it is turn the loco over,if you don’t have a cradle get something that will support it without damaging it. Then I use a piece of powered track ( I made mine by cutting 4″ off a piece of flex track and soldered a piece off wire on each rail ). Then I turn the power to about half speed and touch the track to the pick up wheels select the wheel or wheels you want (remember you can’t do all of them) apply the snot with a toothpick or similar by touching it to the wheel and the momentum of the wheel will give it an all round coating try to get it a smooth and even as possible but remember not to cake it on then leave it over night to cure. If you find you don’t like it it will just peel off and no harm done. I have used it a few times with different results just be careful not to put to much on . Good luck Graeme.

    is on the right track
    the best wheels to put the snot on is the rear axle or both rears if you have two trucks, booth wheels on the one axle keeps a even pull if just one wheel on the axle the truck will want to pull to the side. and if you have a small engine you can run into a problem with electrical pick up. you will have to keep the wheels and track clean to prevent stalling
    If you are running DCC it is a good idea to install a Keep alive to prevent electrical pick up problems
    I do repairs DCC/LED installs etc If you need more info or work on your engines let me know at trplam@gmail.com

    You fellows have me stumped. I mam familiar with GUINNESS to remedy most things but whatever is this bull frog snot ?

    • Sheldon Clarksays:

      Like it!

    • Train Doctorsays:

      frog snot comes in a small bottle it is a rubberish thick liquid that dries then it is sticky to the rails

  • Sheldon Clarksays:

    Peco in UK make a servicing cradle & wheel cleaning brushes & scrapers that would be good for keeping the wheels rotating as the wonder material cures/dries.

  • Barriesays:

    I have used BFS on N scale locos with good results. Because it is pretty thick, I mix a little with boiling water to thin it out. I apply it with a tooth pick tip while the wheel is turning at a moderate speed. Don’t run the loco too fast when applying otherwise the BFS will centrifuge up to the flange side of the tyre. Dip the tooth pick tip in the thinned down BFS and place it on the middle of the tyre as it is spinning away from the tip and let it pull the BFS off the tooth pick and on to the tyre. Have enough on the tooth pick to coat the rim with a thin layer. Don’t go back and apply a second coat as it will not lay flat and the first application of warm BFS will solidify quickly as it touches the colder wheel. If you don’t get it right the first time, peel it off and start again. The secret is to lay it down in one quick application without ‘working’ it. Wear a pair of strong magnifying glasses to help see whats happening. I haven’t tried applying it to HO locos so the process may be different.
    Good luck.

    I have used bullfrog snot on my tender drive hornby loco’s and for me it has worked excellently,however I fear I may have to take out a mortgage to buy the next bottle,the last time i saw it for sale on the internet it was about £63 per bottle.must be the exchange rate.

  • W Rusty Lanesays:

    I have heard a lot about Bull Frog Snot with a lot of modlers liking the product. It´s quite expensive for me to use so I just bought some traction tires (little rubber bands) to put on the wheels of the locos requiring traction tires. This has worked well for me. Maybe one of these days I will try some BFS but I only have a couple of locos that require traction tires and BFS would be cost in-efficient for me. The traction tires were more economical.

Use Tiny Railroad Micro Controllers

A micro controller is basically a small programmable computer device to help the model railroader “make things operate.” It is clever way to realistically replicate the movements, actions and functions you are likely to see on a full size railroad.

It’s YOUR Railroad!

Your rolling stock and locomotives might actually be the center of attention on your layout, but the scenic features that surround and envelop your layout is what's likely to make your train setup stand proud of the rest. Your selection of scenery and structures will add an element of customization that will make your railroad truly unique.

Scenery, structures, and fine detailing is a fundamental aspect of any good model railroad, particularly if it is intended to replicate a true-to-life railroading scene. How realistic or authentic you make your railroad is entirely up to you... and you alone.

Some enthusiasts like to replicate every tiny detail so as to accurately depict, in every aspect, a miniaturized version of a real life scene.

Others in this hobby adopt a more "free-style" approach and choose to mix and match accessories and features they personally prefer. Even though the purist will possibly be unimpressed with unrealistic or out of context elements, it is YOUR railroad layout so you can make it anything you personally want!
