Fastech 360

Japan is beginning trials of the newest and sleekest version of its Shinkansen "Bullet Train" which boasts ear-like air brakes for emergency halts.

The latest model will travel at up to 360km/h (233mph) but is capable of reaching even higher speeds.

Its ears - half-moon shaped fins along the roof - are designed for rapid braking in the event of earthquakes.

The train, expected to be in service by 2011, is a highly-developed version of the original Bullet, launched in 1964.
