I just replaced a #4 turnout with a # 6 to ease the transition from one track to a siding. I've always had some cars derail there. Test running it w/o power all of the cars that formerly had a problem negotiating that turnot now glide through smoothly.
Powering up a locomotive, however, led to frustration. The engine moved as usual until the wheels passed the end of the new turnout and rolled onto the next section of track. Then it all but crawled despite my turning up the power pack to full. I checked wiring, the loco, etc. Finally I bit the bullet and pulled out the turnout I just installed (fortunately hadn't ballasted yet) and examined it. I noticed one of the rail joiners looked pretty tarnished. I replaced it with a cleaner one and that did the trick! Sheesh!
