Old Track Vs New

[AntonioFP45]

Sounds like you have the "sectional snap track". If it's nickel silver, you can probably reuse it. Make sure that you clean it. Some modelers use bright boy blocks or rotary tools. I prefer a terry cloth towel soaked with rubbing alcohol. I learned years ago that putting too many scratches on the rails will lead to grime build up in time. Also test your rail joiners. If you see that they slide on and off the rails easily, then either squeeze the sides gently with pliers for a "snug fit" or simply replace them. They're pretty cheap at local hobby shops. Also consider soldering jumper wires between stretches of sections to insure good conductivity. Lastly, if you see yourself getting "deeper" into this hobby, consider replacing the plastic wheel/axle sets on your rolling stock with metal wheels. Track will stay much cleaner and the cars will roll better. LifeLIke/Proto sells some great wheelsets. One package re-equips 3 cars. $8 most places, probably even cheaper on the web. Hope this helps!

I have a mix of brass and nickle silver on my layout (prebuilt modules, which I didn't
want to rip up). Both work, but brass will need cleaning more often. I've noticed
since quit smoking some yars ago, track stays much cleaner!

If it is nickel silver, I'd try some of it out before committing to it. It may need cleaning. At a minimum I would use a wire brush in a moto tool to clean the ends before putting on the rail joiners and use new joiners. I know that nickel silver is supposed to conduct electricity through the oxide, but this will certainly test that out. Also, after thirty years you may have a build up you don't want to get on your wheels. But hey with the prices these days I'd certainly set up a test loop.

If your track has nickle silver rails and plastic ties, go ahead and use it.

If the track has brass rails and/or paper fiber ties, get new track.

Your older track probably has code 100 rail which in HO is equivelent to 155 lbs. per yard rail, which was exceptionally heavy and AFAIK, was only used on parts of the Pennsylvania Railroad. Now might be the time to convert to code 83 which is closer to the typical 132 lbs. per yard rail.

Starting again after 30 years [new younger son], I have 30 year old track. My question, should I try to build using this old track or purchase the new?
Thanks,
