I think that we have allowed ourselves the indulgence of posting trains before.

RAILWAYS IN UZBEKISTAN
DELUXE TRAIN "AFROSIAB"

http://www.centralasia-travel.com/en...ansport/trains


Quote:
The aerodynamic front design of the train allows optimizing the action of wave pressure and crosswind, reaching maximum speed.
Blame the Spanish for it's looks.

Quote:
The train was developed using the most advanced technologies in Spain by specialists of “Talgo”.

I'm surprised to see sharp transitions on the leading edges being called "aerodynamic".

Trains have the added handicap of passing close by stationary objects close to the tracks, and even people waiting in railroad stations where it does pass through at speed. Much is done to prevent a sideways blast; rather the air is forced upwards, out of harms way.

trains

Another consideration facing train designers is eardrum protection for the passengers as the non-pressurized cabin higher speed trains enter,or leave a tunnel.
So much can be done with the tunnel ends themselves,building like a muzzle brake,but long,organic shapes help with the pressure spikes.
Also,since the trains run 'forwards' and 'backwards',the 'nose' can make a fine boattail.
Japan's Shinkansen has experimented with nose/tail extensions up to 57-feet in length.
Air-brakes too!

Good point, an image of that is on their website.

Rust Heinz, the ketchup king, designed not only the 1938 Phantom Corsair (a weird car in its own right) but this delivery truck, called the Comet. As Daniel Strohl has pointed out, the 1938 Comet was built on an Autocar chassis, and if Rust Heinz hadn’t died in a car crash in 1939 at age 25, the company would probably have commissioned a fleet of these vehicles.

In an alternate 1950s, they hit the used car lots alongside the Helm's Bakery trucks. Or the Chrysler front-wheel drive Beetle-sized car with the 5-cylinder radial engine.
