Improvement of MagLev or Dynamic Electromagnetic Suspension.
Its wellknown that MagLevs uses static electro/magnet field to levitate trains - D, E, F. Fig. 1, 2.
It takes a large amount of electric energy to lift up heavy wagon. Because the shift is very big - about 10 cm - S1. Fig. 1.
I suggest dynamic electromagnetic suspension with additional vertical linear engine - A, B, C.
Working like usual linear engine but vertical, it creates vertical force, lifting the wagon.
It can create a big lift force (moment) with a smaller electromagnets.Because the shift S2 Fig. 2 is ordinary for ordinary electric engines ( maybe 1 cm) and much smaller than S1.
H, I, J usual linear electric engine to move train horizontally.
If A, B, C is not strictly vertical, then it creates a horizontal moving force also.
Also we can take off D, E, F and H, I, J emagnets if we use many equal sizes magnets only and commutate them in special order.
