I'm going to make a foray into some prewar tinplate and have a question about rolling stock. I recently purchased a tender to go along with my 226E engine and would like to get some rolling stock to compliment it. My present collection is a combo of modern command stuff along with a lot of postwar, so I know very little about tinplate. I've read some posts on various threads saying that the 4 wheel rolling stock doesn't track well over switches and has a tendency to derail. Is this true and should I avoid them? Any comments or tips about rolling stock and what to look for would be appreciated.
