Check out the MagLev train in Japan

MagLev is a method of transportation that replaces wheels and axles with magnetic levitation to gain lift and propulsion.

MagLev (which stands for “Magnet Levitation”) can provide a number of benefits over a traditional rail system: due to reduced friction, wear and tear on the rails and wheels are greatly reduced. This cuts down on the amount of maintenance work required and allows the train to travel at greater speeds for longer. They’re also less affected by weather conditions -- so no more delays due to wet leaves on the rail!

The downside, however, is that they a MUCH more expensive that traditional or high speed rail.
