No that's true normal N scale models won't run on these tracks unless self powered as they normally draw their current from the metal tracks.
However having said that these tracks are the correct scale, so could be used for display of static N scale models as produced in Japan or similar.
In a similar vein these trains could potentially travel on metal tracks, although how you'd charge them is another issue lol!
But they are cool and great for little kids you don't want to let get their hands on your real N scale models.
BTW - Fleishmann do make the DRB 01.10 in N scale, in fact they have 3 variants apparently as well as a 01.11, the cheapest is (take a breath) £169 and that is only because it is on special, normally they are all over £200
