This is a tube traveling vehicle I assume? There were plans for these things in several countries at one point but the expense of making the tunnels and maintaining a vacuum to travel at that speed was considered anti-economic at the time. Today you see people like Elon Musk proposing things like the Hyperloop which has much the same issues though. 1000 kph is basically supersonic speed so all the proposals that I can remember for that basically used a lower air pressure or vacuum because of that.
If you look at the Japanese SCMaglev which is a practical design which is supposed to reach production it is still hideously expensive even though it travels at a much lower speed.
