@bobotech posted:I'm a little confused. I'm not very familiar with the OO gauge but I always understood OO guage to be HO gauge track with rolling stock/engines that were a percentage bigger, like 10-20 percent larger.
Is this like Marklin 3 rail track?
Stud center rail? No; there is normal 3r HO/OO. It is actually round top tubular track sometimes too (vs solid T rail). My vintage Junior 3r 00 is plastic roadbed and I think it is 0-27 to add to contusions..... and spellwreck makes another funny
