She runs!
I still have to fix the headlight, but I thought you all that got caught up in my Marx Track story, would like to see the train is running again, although I committed the sin of using Marx O34 (straight sections) and O27 (curves).
I just wanted to see her run again smile: !
Forgive the mess in the video. Also, I acquired a Marx (0-4-2) steam locomotive. Surprisingly I got the original smoke fluid (a very small amount), I could not help myself, I put some fluid in that engine and it runs too, and yes it does produce smoke. It will run with the tender car on the current setup, but derails if more than 3 cars are behind it. Yes, I know that locomotive comes from an O34 set (set #9615).
I also want to thank everyone for the advice and information.
