Underground - and the already ridiculously high costs would explode even more. That the train currently rides on a bridge-like elevated track, 4-5 m above the ground, is on security measure to prevent something falling on the track and blocking it. Currently it seems that it was human error indeed.It's a loced situation - it will not become cheaper when it is not sold more often, but it will not be sold mor eoften it it does not become cheaper. I think noone currnetly would be willing to bear the additional costs of building such tracks underground (which also would be visually less intrusive).
