BiLevel coaches have an aluminum body on a steel frame. They are 15 ft 11 in (4.85 m) high, 9 ft 10 in (3.00 m) wide, and weigh about 61,000 kg (134,000 lb). [ 1 ] They hold 136–162 seated passengers and 276 standees (depending on coach series and seat configuration) and have two pairs of doors on each side that allow the entire coach to be ...
Voiture à impériale. Double deck carriages date to at least as early as the second half of the 19th century.

An orthotropic bridge or orthotropic deck is typically one whose fabricated deck consists of a structural steel deck plate stiffened either longitudinally with ribs or transversely, or in both directions. This allows the fabricated deck both to directly bear vehicular loads and to contribute to the bridge structure's overall load-bearing behaviour.

It remains the only double deck train to have ever operated in Melbourne. The train's name stood for "Double Deck Development and Demonstration." [3]
Planar transformers [1] are high frequency transformers used in isolated switchmode power supplies operating at high frequency. As opposed to conventional "wire-wound-on-a-bobbin" transformers, planar transformers usually contain winding turns made of thin copper sheets riveted together at the ends of turns in the case of high current windings ...
The development of such homogeneous steel resulted from testing which showed that face-hardened armor was less effective against high-obliquity glancing impacts. Around 1910, Carnegie Steel developed a new nickel-chrome-vanadium alloy-steel that offers improved protection over the prior nickel steel armor, though vanadium was no longer used ...
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece. [1] A planer is similar to a shaper , but larger, and with workpiece moving, whereas in a shaper the cutting tool moves.
