Railrunner wasn’t even “Built”.
He ‘BOUGHT’ (That is, the next five generations of NM Taxpayers will be paying for) some existing but essentially unused freight train tracks. Then he bought a used engine & cars; gave them a paint job and put some duct tape on the slashed seat covers.
He does plan to build some more track, but it is going to take 10 years and ten times as much money as planned before it is ready to roll (if ever).
