A very small amount of heat, as compared to an automobile's wheel. Entirely steel wheels have much less rolling resistance than a wheels with big squishy rubber tires.
Almost all trains have wheels, although there do exist trains that use magnetic levitation and do not require wheels.
Yes, bullet trains have wheels. They run on rails, just as conventional railroad locomotives and cars do. The trains that operate by magnetic levitation, the so-called MagLev trains, do not have wheels as they ride on a magnetic cushion.
Maglev trains are faster than normal trains because they use magnetic levitation to reduce friction between the train and the tracks, allowing them to reach higher speeds. Additionally, maglev trains do not have wheels, which eliminates the rolling resistance experienced by traditional trains on tracks.

There are four wheels to Bowflex-SelectTech-Dumbbell-Stand and two wheels can be independently locked with help of latch to prevent the stand from rolling
