Yes, but your dealing with a high power system that requires power
storage for coil discharges all along the length of the rail, but the
goal of the discussion is to also use the rail to receive incoming
payloads from Earth.

No ramp needed. The package will be in a trajectory the whole time it
is going through the track, and so long as there are no mountains in
the way when it exits the rail, does not need to be more than a few
dozen meters above the regolith average elevation.
