The invention provides a longitudinal two-way flow guide type bullet train head which comprises a fairing and a flow guide plate, and is characterized in that the fairing is in a duckbilled streamline shape which has the characteristics that the front end is transversely flat, the longitudinal diameter of the front end is gradually increased from front to rear, an upper arc is large, a lower arc is small and two sides are flat; the flow guide plate is a longitudinal vertical flat plate which blocks the two sides of the fairing and extends outwards. Comparedwith the prior art, air in front of a bullet train during running of the bullet train is diverted upwards and downwards by the fairing and the flow guide plate, so that transverse flow and eddy flow caused by compressed air are limited at the top of the bullet train in open space and the bottom of the bullet train in fixed space, less disturbed air is generated on the two sides of the bullet train, and the transverse width of air stream is relatively small; the air stream diverted to the upper part of the bullet train is relatively easy to disperse due to the open space; the air stream diverted to the bottom of the bullet train difficultly forms the transverse flow due to the ground effect, so that the bullet train is slightly jolted; the relatively high-speed air stream is reduced on the two sides of the bullet train, so that the influence of nearby dynamic and static large-sized objects is reduced, the left-right swing is slight, the bullet train is relatively stable, the attractionto nearly dynamic and static small-sized objects is reduced, and the bullet train is relatively safe.
