Man, I love trains! 
I do too. I've been wondering, however, do children today? You do not see many trains nor is it a common mode of transportation anymore (at least in Canada that was defined by railways following the wild west days - I think it was to a similar extent in the usa, as well).
Maybe this is why Playmobil is getting away from trains. Maybe it is also the fact they can not use transformers in Europe anymore (hence the switch to R/C).
