Is that assuming there will not be major repairs?
Fewer major repairs is the way they save you money. Fewer moving parts, less friction, less wear and tear. All the energy savings gets tossed out the window in the interest of going faster, in the ones we've made so far anyway.
There may be fewer moving parts but that does not necessarily mean cheaper/less repairs. Current railway parts (especially wheels) are fairly low tech and easily fixed. What if the cooling of a superconducting magnet fails? Thatβs expensive.
Sure, I didn't say they never require maintenance or anything. Simply that over a long period of time they become cheaper to operate, after taking into account repair and replacement costs.
If you don't take repair and replacement costs into account, they become more expensive. This is probably another reason there are not many of them. Repair is where they save you the money though, due to how infrequently they require it.
