Can Maglev trains ever reach escape velocity?

What you are proposing is known as a mass driver, and the concept goes back at least to the 1960s. It was discussed by Gerard O'Neill in the 1970's as part of a method to build space colonies, and ...

Can Maglev trains ever reach escape velocity?

Yes, maglev trains / mass drivers can potentially reach escape velocity, but a mechanical centrifugal launcher may be more viable. Lunar escape velocity at ground level is 2.38 km/s. Orbital velocity ...
