Steel wheel on steel track

A railroad that train steel wheel rolls on steel track. It is the most popular rail transportation.  Normal railroads can transport heavy freight (link) and passengers, but the speed are lower than 250km/h. High speed rails can run faster, but cannot transport heavy freight (link).

One goal of this society is to make high speed rails be able to transport heavy freight in technology. 

In practice, on a steel track, 

a vehicle with steel wheel driving run at speed of 574.8 km/h in 2007 (link), 

a vehicle with rocket driving run at speed of 10,326 km/h, Mach 8.5 in 2003 (link).
