I would much prefer electric trains from Playmobil!
They were electric when I was growing up, but I had HO trains and I really admired the Playmobil ones, but they seemed like "toys" in comparison (I was at that age when you transition out of little kids' toys (Playmobil) and into bigger kids' toys (scale models)).  There was also the cost comparison.  
Of course, now that I'm older I clearly see the error of my ways and I do wish I would have gotten electric G scale trains.  
I do have RC trains - however, the way Playmobil has been discontinuing the RC line the other year it makes me wonder how much longer it will be around...  (Was that merely a test to see how much response they get to see if people are still interested in them?  Or a sales-increase ploy?  Or?)
I wonder with the PCC we could voice our interest in Playmobil bringing back electric trains?
