摘要： A system for realizing emergency rate reduction (SOS). A receiver initiates a short rate-reduction request, and communicates that request to a transmitter. The transmitter initiates an operational switch to an adjusted transmission reference (i.e., a new bit/gain table), by sending a signal to synchronize the operational switch for both the transmitter and the receiver. The adjusted transmission reference may be calculated using a formula, from a current bit/gain table, or may be a predefined bit/gain table. The parameters of the formula may be predefined, calculated during initialization, or determined in real time during SOS.

The steel rail includes 0.40-0.64% by weight of C, 0.10-1.00% by weight of Si, 0.30-1.50% by weight of Mn, less than or equal to 0.025% by weight of P, less than or equal to 0.025% by weight of S, less than or equal to 0.005% by weight of Al, more than 0 and less than or equal to 0.05% by weight of a rare earth element, more than 0 and less than or equal to 0.20% by weight of at least one of V, Cr, and Ti, and a remainder of Fe and inevitable impurities. The steel rail manufactured according to the method of the present invention maintains the strength and hardness of the existing steel rail for the high speed railways, while enhancing the toughness, plasticity and yield strength, and an energy value required for initiating and expanding microcracks formed at the surface of the steel rail due to fatigue is increased, and thus under the same conditions, the rolling contact fatigue property of the steel rail can be improved, thereby finally improving the service lifetime and the transportation safety of the steel rail.
