High speed Linear motor train

In Japan they are developing the Linear motorcar. The Linear motorcar is a high speed "Linimo", a Linimo is a magnetic train that doesn't have wheels but hovers, it is also called maglev.
We went to see the test track at Otsuki, it is currently 42km long. They will try to extend it to Tokyo before the Tokyo Olympics in 2020, One day it will go all the way to Osaka, which is hundreds of kilometers.
First we saw it outside, it was gone in a second and was very loud. it was so fast we couldn't even see it properly. Then we went to the exhibition center so we could see different models of it more clearly.
When we saw the Linear motorcar, it went 300km/h but it can really go up to 500km/h.
