>>11285824It's not THAT bad. Rails, pistons, a bit of redstone. The real problem is the amount of time it takes - you have to build it perfectly.
Also you can't repair a broken segment mid-track, so if a ghast hits it halfway you have to tear apart half the fucking track to fix it. It also needs to be on level ground. So you build it on the nether roof and ghast proof it, and build it VERY carefully to make sure you don't make any mistakes.
Could one of the girls build a track like that? Absolutely, it's not that complicated or resource intensive. Would they take the time to figure out how to get on the Nether Roof (or worse, flatten a large amount of the nether and protect the track) and then build an entire segment of it? Probably not.
