Quay Valley, California
In March 2015, Dirk Ahlborn, the CEO of Hyperloop Transportation Technologies (HTT) in El Segundo, California announced a plan to build a hyperloop test system at the Quay Valley site. Ahlborn indicated that construction could begin in 2016 to be completed in 2017 with the first rides to begin in 2018 if his company can raise $100 million in funding. The company has said that this track will be a fully working and operational creation of the hyperloop, but that running speed will be reduced on the shortened track from Hyperloop's full potential. It is not decided whether a 5-mile loop or straight section will be constructed, and it may cross the Interstate bisecting the site. Ahlborn said that speeds up to may be possible. Quay Hays expects to break ground on the new community in 2016, including a working version of the Hyperloop, estimated to cost $100–150 million.
Baltimore Belt Line
Reconstructing the Howard Street Tunnel to accommodate double-stacked intermodal containers had been once thought to cost $1–3 billion. However, in April 2016, a $425 million plan was revealed that would create the needed of additional clearance in the tunnel by trimming and notching its arched ceiling, lowering its floor, and using steel crossties, which have a lower profile than wood crossties. The Maryland Department of Transportation subsequently applied for a $155 million FY2016 FASTLANE grant to help fund a project based on this lower-cost plan, but the grant was not received. In December 2016, MDOT reapplied for a FASTLANE grant of the same amount in the FY2017 round of funding. In addition to the federal funds expected from the grant, the State of Maryland would contribute $145M, and CSX $125M, towards the cost of the project. In expectation of the grant funding, CSX is investing $25M in the tunnel$21M to improve its water discharge system, and $4M for engineering and design of the clearance improvements. The project, which would also increase the clearance at nine bridges north of the tunnel, would last 4–5 years (due to having to be scheduled around active rail traffic), create about 500 construction jobs, and would result in 178,000 containers per year being moved by rail from the Port of Baltimore instead of by truck. Maryland Governor Larry Hogan said that the state would explore other funding solutions if the FY2017 FASTLANE grant is not received.
