Wind-Powered Cargo Ship Sets Sail : NPR
January 22, 2008Welcome to the "green" age of commercial shipping. A German-made cargo ship will soon set sail, literally. The ship will be carried over the water partly by wind power. The sails are from a German company called SkySails, and they're really more like giant parachutes. Each sail is about the size of a football field.

This took half the time it would have taken had the journey been made by sea, which is how most of China's goods enter Europe currently.
That's pretty slow for a train though: at 60km/hour average it would have taken just 7 days, 16 days is an average of just 26km/hour!
The answer should be 13 km/h.
13 km/h is a decent jogging speed or a slow bike ride. So for speed, a pony-express of transport bikers can beat boats from China to Europe.

However you are presuming that bikes are efficient for locomotive power, they are not. They are efficient for moving people, but for moving cargo I expect wind or solar to be a better option (including embodied resources).
An idea I tried to promote on a disused rail line between two towns which had a fair amount of freight exchange was to buy a few rail container wagons, cover their roofs in solar panels, with a controller to connect to a motor. Each wagon would be self powered, whirring along at whatever speed it could achieve (perhaps 5km/hour) travelling to the other town. It could then provide pretty much free cartage. Of course it would be too slow, and there were all sorts of objections with respect to safety, vandalism, theft, transloading, cost, getting stuck under bridges.
We could imagine trains powered by teams of fit peddlers (peddling their bikes :) sitting inside a hollowed out locomotive.
aaargh, down into the galleys with ya matey!
love your idea with the solar trains, i see horse-barge-canal combos probably making a big comeback in some parts of the world, ditto woodgas transportation and low tech windmills for wells and irrigation and enough juice to run dialup internet.
land- and ice- sailing, pedal trains. mules will make a massive comeback...
