Why does Duplo have so many more different rail pieces than Lego System?

I came across a local Lego store and got stuck in front of the Duplo showcase. Just look at this amazing bridge with proper track slopes! Meanwhile, we have only a single straight, a single curve, a switch, and an obsolete double crossing for regular Lego System. Meh. submitted by /u/mr__equus [link] [comments]
