It would be a cheap and cost efficient way to link UOR:North with Site B.I tend to agree, but only because of how much maintenance monorails need. That's where they speed a lot of money. Buying a new fleet would be fairly cheap and would solve a lot of headaches fast.
They could easily use the monorail route and the Monorail stations for a Gondola line to replace it though. Gondolas are much cheaper than monorails and arguably more efficient.
