China introduces bullet trains that travel in Subzero image

China debuts new high-speed bullet trains equipped with chromium-molybdenum alloy bolts which that operate in subzero temperatures. The high-speed bullet train called the CR400AF-G train that can work in exceedingly cold climates with a speed of up to 350 kilometers per hour in temperatures as low as -40 degrees Celsius. The project is part of the state-owned China State Railway Group's Fuxing series of high-speed electric multiple-unit trains.
