According to the original design specification, the goals for mean time between failures were set at 1,400 hours or 21,000 miles (34,000 km) for the propulsion and auxiliary electric systems, which assumes average operating speeds of 15 miles per hour (24 km/h); 1,500 hours or 22,500 miles (36,200 km) for door and step systems; and 4,000 hours ...
Concept art of hyperloop inner workings. Hyperloop is a proposed high-speed transportation system for both passengers and freight. [1] The concept behind the Hyperloop originated in the late 17th century with the invention of the world's first artificial vacuum, which led to designs for underground rapid transit systems powered by pneumatics in the decades that followed.
U.S. Army truck convoy in Mexico, 1916. The Transcontinental Motor Convoys were early 20th century vehicle convoys, including three US Army truck trains, that crossed the United States (one was coast-to-coast) to the west coast. The 1919 Motor Transport Corps convoy from Washington, D.C., to San Francisco used the incomplete Lincoln Highway.
Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour. It is used in the United Kingdom , the United States , and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.
San Francisco; started 1995; number in service: 27 [74]. The F Market Line (historic streetcar service) in San Francisco, opened in 1995, runs along Market Street from The Castro to the Ferry Building, then along the Embarcadero north and west to Fisherman's Wharf. This line is run by a mixture of PCC cars built between 1946 and 1952, and ...
1 gal-US (3.785 L, 0.833 gal-imp) of fuel can move a ton of cargo 857 km or 462 nmi by barge, or 337 km (209 mi) by rail, or 98 km (61 mi) by lorry. [142] Compare: Space Shuttle used to transport freight to the other side of the Earth (see above): 40 megajoules per tonne-kilometre. Net energy for lifting: 10 megajoules per tonne-kilometre.
Different speed limits exist for heavy goods vehicles (HGV) but the limit for HGV is country dependent: while most Eurasian and American countries might use the Vienna convention's 3.5-tonne limit, other countries in North America, China, India, Australia or Ireland might use different weight limits.
For example, the Siemens S70 LRVs used in the Houston METRORail and other North American LRT systems have a top speed of 55–71.5 miles per hour (88.51–115.1 km/h) depending on the system, while the trains on the all-underground Montreal Metro can only reach a top speed of 72 kilometres per hour (44.74 mph).
