The Faller E-train and Playtrain ranges were nearer to 1/24th scale, ie G scale…..
Axleboxes, wheels, door height, seats etc. are closer to a metre gauge prototype in 1 : 32 . But remember, they were intended as toys, not finescale models. BTW, G-Scale refers to 45mm gauge.
Faller came with 32 mm.
True, Faller and Playmobil gave up their trains in the last century. Like train makers in other scales, they realized, you cannot make much profits with trains for children these days anymore.
Most children never have seen a real train in their life. At least not one of these smoking and stinking beasts, adult customer love.
But don´t worry. There are quite a few companies left which offer model trains in various scales. Even for narrow gauge. In GB, Scale Link comes to mind. And a few new ones appeared at the market. For 1 : 32 scale I think of KM-1 and Tobias Feld just to name two of the larger ones. Very succesful firms. And there are the many cottage or garage firms.......Stroll over the next exhibition with open eyes.
