The train ascends the mountain at 2.8 miles per hour (4.5 km/h) and descends at 4.6 mph (7.4 km/h). Steam locomotives take approximately 65 minutes to ascend and 40 minutes to descend, while the biodiesel engines can go up in as little as 36 minutes.
Reducing the weight of the bike + rider by 1 kg would increase speed by 0.01 m/s at 9 m/s on the flat (5 seconds in a 32 km/h (20 mph), 40-kilometre (25 mile) time trial). The same reduction on a 7% grade would be worth 0.04 m/s (90 kg bike + rider) to 0.07 m/s (65 kg bike + rider).

NR-1 could travel submerged at approximately 4 knots (7.4 km/h; 4.6 mph) for long periods, limited only by consumable supplies—primarily food. It could study and map the ocean bottom, including temperature, currents, and other information for military, commercial, and scientific uses.
Super Stock and Drag Racing Magazine recorded an 11.62 second/122.15 mph (196.58 km/h) 1 ⁄ 4 mile (402 m) in a professionally tuned ZL1 Camaro with open long-tube S&S equal-length headers, drag slicks, and minor suspension modifications, driven by drag racing legend Dick Harrell. Using Patrick Hale's Power/Speed formula, the 122.15 mph (196. ...
The rudder had been damaged by depth charges, so the submarine circled clockwise at roughly 7 kn (13 km/h; 8.1 mph). The commanding officer of Chatelain saw the submarine turning toward his ship and thought that it was about to attack, so he ordered a single torpedo to be fired at her; the torpedo missed, passing ahead of the abandoned U-505 .
The submarine had a maximum surface speed of 18.2 knots (33.7 km/h; 20.9 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). [2] When submerged, the boat could operate for 64 nautical miles (119 km; 74 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 12,000 nautical miles (22,000 km; 14,000 mi) at 10 knots ...
