I'm a casual Lego enjoyer and decided to research some old sets and found out about the old monorail system.

My question is why was it discontinued? It was a pretty neat system and I could see something like it working well with modern themes (mostly Lego City), and why was it in so few sets?

According to https://forum.brickset.com/discussion/comment/57906/#Comment_57906 :

The reason LEGO has stopped making monorail is threefold,

One, the motors and track molds ran out and would be very expensive to replace.

Two, no monorail set ever made any money, in fact despite trying several different types at high price points they all cost more to produce then they were sold for.

Three, kids these days don't see them as exciting, they are from theme parks or airports, not a futuristic thing at all, in fact pretty boring.

On the subject of molds: according to https://bricknerd.com/home/lego-monorail-bring-it-back-or-build-your-own-7-6-21 ,

The molds and the motor aren’t available anymore because they were produced by a contractor that no longer exists.

    Changing times is certainly true in lots of cases. When I was a child, I saw vector polygon graphics as the wave of the future in video gaming. Nowadays, they are firmly retro and a sign of the 1980's. Commented Feb 1, 2023 at 2:31
  • Why didn't they set the price based on the production cost? Commented Feb 1, 2023 at 20:14
  • @SolomonUcko I would presume that sales would be minimal at a prices so high. Commented Feb 1, 2023 at 21:30
