They rely on precise track. Rolling resistance of nicely round steel circle on nicely smooth steel rail is negligible to rubber-tarmac contact. The other thing it utilizes is the locomotive weight. The contact pressures in the wheel-rail contact are very high and they use sand to increase the traction.
