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 emptied in 90 seconds.
He’s also trying to move away from the “double decker” and “double level” label, suggesting the concept could be referred to as “3D seating.” While Núñez Vicente envisages a future ...
In software engineering, double-checked locking (also known as "double-checked locking optimization" [1]) is a software design pattern used to reduce the overhead of acquiring a lock by testing the locking criterion (the "lock hint") before acquiring the lock.
