Hyperloop and high-speed rail connecting major cities, traversing coasts or bisecting large states were promised, hinted and proposed throughout 2019, but the technology has yet to leave the station. 

Nevertheless, hyperloop and bullet train technologies continue to be a hot topic in construction. As more possible locations for hyperloops are proposed, we learn more about the costs and demands of implementing the ultra-high-speed rail system. 

The Boring Co., owned by Elon Musk, made headlines this fall when it began underground work at the Las Vegas Convention Center. According to the Las Vegas Convention and Visitor's Authority, the people mover could be the first step towards implementing a larger underground railway near the Las Vegas strip.

Even then, AECOM, who evaluated the possibility of a Texas hyperloop, said that at best implementing the high-speed rail would be feasible a few decades off. 

Meanwhile, contracts for massive high-speed and bullet train rail lines are being signed and shovels are soon to hit the ground. Other projects have been derailed amid funding woes. One thing is certain is that the segment will be hot for contractors next year.

Here we take a look back at stories about hyperloop technologies, as well as other high-speed rail technologies in light of construction proposal and feasibility to see how far the discussion has come in the last year.
