Southern Pacific Switching Layout

[torikoos]

I am using the older(Non DCC-friendly) Walthers Turnouts, But I will be sure to build all future layouts with Pecos

I am starting to think that my tracks may not be as clean as I thought, since the engine runs fine over newer sections of track.
What's a good way to clean track?

Please see my post, a few days ago. you may have overlooked it. :-) (at the bottom of page 18 of this thread)

You need something that is not too aggressive, but has good degreasing capabilities.
The friendliest is good old washing up liquid, heavily diluted of course (say a tablespoon in half a gallon of water), dip in a rag, and wipe the rails with this.
A bit more agressive is the use of 90% alcohol, but you need to be in a well ventilated space! And as with any chemical, read the safety precautions etc.! Again, put some on a rag, and wipe the rails.
There's probably also dedicated rail cleaners, but they are probably based on similar isopropyl alcohol.
You can also use some nail polish remover, which is acetone based in many cases, this will also work fine, again use on a rag.
