No, the scale is 1:29 (3 times HO) for the locomotives and rolling stocks while they cheat a little bit with the tracks, they use the 45 mm instead of ~52mm. So you can use the stuff on most of the popular I or IIe tracks which are usually for DC.
H0 is 1: 87 scale (16 mm gauge) , 0 is 1:43 (32 mm gauge), I is 1:32 (45mm gauge), IIe is 22.5 :1 (45mm gauge) .
