I think it is still the Japanese bullet train.
There are several manufacturers of fast trains all over the world. Some of the manufacturers that produce the fastest trains include Bombardier Alstom, Shinkansen, Caradia, and Siemens.
Some of the fastest trains in the world are Belgium's HSL-1, China's CRH380A, Germany's Transrapid TR-09 , Japan's Shinkansen train, and Shangai's magnetic levitation (maglev) train.
Its not the speed over the roadbed that counts (all 3 are about the same) but the fact that unit trains do not need to be classified at each intermediary yard that makes them the "fastest".
Fast I am assuming.

The fastest trains in Portugal are Alfa Pendular trains, which can reach speeds of up to 220 km/h (137 mph) on certain routes. These trains operate on the main railway lines connecting major cities like Lisbon, Porto, Braga, and Faro.
Trains
The fastest train in the world is located in China. The CRH380A tops out at 302 miles per hour. Next would be the TR-09 in Germany that tops out at 279 miles per hour.
It depends what country you are in. France has the fastest normal running service in the world at the moment at 300km/h (180mph) and this extends to the UK's St Pancreas International and other neighbours to France. The UK has trains that run at 200km/h on the main lines but it is possible to travel at 250km/h and the U.S is fairly undeveloped for train technology, the fastest trains run at 150km/h most of the time.
There are 2.4 Steam Trains in the world as of 2012.
Airplanes are the fastest way to travel a long distance. - Over short distances, some trains may be faster
