One difficulty holding back the further implementation of hyperloop infrastructure is the fact that the new mode of transportation doesn’t fit neatly into existing regulatory framework. In response to a question from Sen. Thune on that subject, Raycroft noted that hyperloop systems were currently under the jurisdiction of the Federal Railroad Administration (FRA). This is despite the fact that certain aspects of hyperloop technology don’t fit neatly into the FRA’s regulatory framework for railroads, including vehicle bodies which are more similar to commercial aircraft. Raycroft said that engagement between the FRA and other agencies within the Department of Transportation could help speed the regulatory process while ensuring that passenger safety remained a top priority. In response to a later question from Sen. Catherine Cortez Masto (D-NV), Raycroft said that, at the current pace, hyperloop technologies would be ready for widespread passenger use during the mid-2020s.
