If we had a train suspended on magnetic levitation, in a vacuumed tube, wouldn't all thrust from the train be accelerative since there is no countering friction?

So my thinking was that the magnetic levitation would counteract the friction on the tracks and the tube being a vacuum would remove air resistance. Is there another source of friction working against force pushing the train forward.

I was thinking of this as a way to surpass the speed of light. Does this happens to rockets in space? I'm assuming the amount of fuel required for this could be a deal breaker. Even without reaching the speed of light, could we reach a speed to achieve meaningful time dilation?

Edit. Sorry for not replying yet guys, just waking up now. Absolutely stoked with the reception, thanks so much for all the answers. From what I've read, it seems that relativity has an answer for everything in terms of preserving the speed of light, you win this round physics. Keen as to read through all the comments though!

The speed of light is not a limit to be broken. It is a conversion factor between dimensions in space and the dimension in time. 

You can go very fast if you have very little mass, but you cannot exceed c because at c, transit time for you is already zero (all space no time).
