I'm VERY new to this fantastic hobby.  I have acquired several engines and various equipment,  I have 1 controller but 2 tracks that I believe are each controlled by knife switches.  How can I wire the 2  knife switches so I can run either one independent of the other or both at the same time.

Just replaced the shaft and the drive gear on this HO steam Loco American 4-4-0 & Tender PRR.  When I set it on the track and power it up, nothing happens.  When I pick the loco up and clear of the track,the tender picks up and  drives the loco(all wheels turn), but then I set the loco on the track and it quits.  Any suggestions??

Last November I bought a Pennsylvania P.R.R (Model 51114) 4-4-0.  I ran it for a couple of weeks, then put it away to do work on my layout.  Two weeks ago I took it out, and tried to run it, but it appears the loco wheels are stuck.  When I power it, I hear something turning (I think in the tender, but nothing turns.. Since I'm new to this, I not sure if I can take it apart to check it, so any help would bwe appreciated.  Thanks

I am new to trains, have a 5x8 layout , some EZ track and some flex.  I have a left hand switch that I cannot get my train to get across.  Keeps derailing at the frog.  Any help would be appreciated.  Thanks
