The main hall shows the evolution of Japanese trains over time.

While the shinkansen (bullet train) between Tokyo and Osaka is actually not that fast (a mere 280kph) due to limitations from the train tracks built for much older and slower trains (the French TGV peaks at 350kph on newer commercial lines), the technology is nonetheless impressive, especially the part where it tries to counter lean in turns to go faster on curves that are too sharp for higher speeds.

What the new maglev will look like

The main hall is of course where all the trains and history are located:

but waiting for 2027, that's a long time to wait...

in the meantime, you can ride the short test line for fun :)

They had plenty of simulators for people to play with and demos. There is a long line for the shinkansen simulator, but to be honest I don't think it's that fun or impressive to drive a train :)

The diaroma showing the shinkansen line going through Nagoya was quite good:

The displays showing how often the shinkansens run in a single day, and then how they are maintained was quite interesting. Watch the movie if you can:

Then plenty of time to look inside all the trains:

Older trains too:

It was a great visit, really worth the time.
