If I run a 2-rail boxcar on 3-rail track, will it blow up?

What is the difference in a 2-rail and 3-rail box car with no electrical stuff?

I see that in ads and I just wondered.

Thanks.

The bigest differance between 2 rail and 3 rail cars is the flanges on the wheels and the type of coupler they have. I have several 2 rail box cars and have replaced the trucks and couplers with standard 3 rail ones.

The 2 rail flanges may not stay on the track for you depending on the type of track you are using.

The wheels of the 2-rail car are insulated from each other.  The car will not blow up; but neither will it operate an anti-derailing turnout nor an accessory or signal using an isolated control rail.

When I was a kid, I had Lionel trains but first I had a wind up train !! I did have a couple loops & a figure 8 and I would still run the wind up train sometimes to make it look like I really had some action going on there !! Though I knew not to turn the transformer on !!

Wouldn't have mattered if you had!

Wouldn't have mattered if you had!

Thanks Bob !!  I never really thought about till now, 50 yrs. later !!  That means then that you could run a windup on the same track as a regular train !!

Thanks, John

I actually have an Atlas 2-rail Gunderson 5-unit car sitting on my temporary layout (which uses Lionel 027 track) and the 2-rail flanges will stay on the track. Of course it derails over the 027-042 switches, but it tracks surprisingly well over most of the other sections and even 054 curves.

Yes, it will..

It's called an exploding boxcar..

Turning insulated wheels in the presence of a magnetic field produce tachyon particles. If you're not careful your whole layout might implode.

Actually 2 rail cars run pretty good on fastrack, Atlas and Realtrax, may run on others as well.  Last Christamas they had a 50 car train of scale hopper cars, with one coupler transition car, pulled by two 3 rail diesels runing on the display layout at the E-town Library.  This was on fastrack.  It ran for hours with no derailments.  Don't recall if there were switches in the line.  Most 3 rail switches are designed so that the 3 rail wheels actually run on the flanges through the switches, so that could be a problem.
