aleatoryw asked:

if the us government greenlit every proposed rail project right now, about how long would it take for them to be operational? is the delay mostly in the paperwork department, or the physical building?

At least 5 to 10 years due to construction and the amount of contractors that would be involved, additionally all of the proposals are currently in the study phase, not the construction phase, so they are going to need time to enter construction. I would say if we are lucky, lines could enter construction in late 2025 at the earliest
