Display cases: 2 rail or 3 rail?

Pickup rollers would rest on the ties so the springs would actually be less compressed than if they were on 3-rail track.  The problem might be traction tires.  The rail head on 2-rail track is narrower than 3-rail track, so there will be more compression pressure (in terms of psi) on any traction tires so they might deform.

I'm sure that somebody on the forum has actually done this and hopefully they will comment.

I always display my trains on 2 rail track regardless of if the train is 2 or 3 rail.  I got some used GarGraves 2 rail track which is the same profile as the 3 rail track with no center rail.  Never had any problems personally.

Good way to go. Looks better spray painted dark camo brown.

I use 2-rail for display when I use track, but I actually prefer the routed grooves when using wooden shelves (I also use some plain flat wooden shelves; all seems to work). My "displays" are varied, including quite a bit of aluminum shelving.

Too much stuff, anyway.

I use MTH Scaletrax for their low profile since their are height limits inbetween shelves. But that may no longer be an option.

Otherwise i'm a fan of the K.I.S. principle/standardization so my goto layout tracks are Atlas O.  My display track may go back to that as well.

My display shelves don't have any track or grooves for flanges.  I haven't had any problems at all.  NH Joe
