The text at the first bullet says that the possibilities have increased
due to the change to the Electric System of Lego.
Without automatic switches and signals the possibilities have more decreased
imho.

I've heard that the main reason seemed to be governmental rules that
restricted toys not to be powered with more than 9 volts.
It has something to do with savety and so.
I don't know how much save 9 volt is in relation to 12 volt.
Back in the fifties and sixties there were even 20 volt powered toys.
Do other toy trains like Fleishmann Magic Train and Playmobil also use a maximum
of 9 volt? Or do these still use the standard of 12 volt as used in model
railroads?

| Speaking of switches, does anyone have any ideas or thoughts on why the lego switches/points are the shape they are? I know they changed shape from 4.5v to 9v but why did they pick the shape they did? Given the constraints of what TLC does and given (...) (19 years ago, 17-May-05, to lugnet.trains)
