The express bus structure that single track short-distance train and direct train combine
Technical field
the invention belongs to traffic and transport field, particularly a kind of passenger train.
Background technology
are rapid for railway transport of passengers, and the method that generally adopts is to improve the speed of a motor vehicle, reduce platform and shorten the dwell time, and this makes the passenger on many small stations can't embody the quick of railway.Particularly for the such short-distance train of subway, reducing platform obviously is more to be not suitable for.Subway passenger up and down, start and the deceleration of entering the station aspect consumed the half the time of about stroke, greatly restricted the speed of railway transport of passengers, also consumed passenger's valuable time.For example the general design and operation speed per hour of railcar is 70 kilometers, but owing to stop in the way, average speed per hour can only be about 25 kilometers.
have two types of patent applications to attempt to address the above problem from the train exchange passenger aspect of not stopping; One type like patent CN200510099734.0 (no-stop vehicle transfer method for passenger train); Its method is; High speed train is placed in the afterbody compartment with the passenger who gets off in advance when station on the way, this afterbody compartment is not got rid of down with not stopping when arriving at a station; Gone up passenger's the car that scoops out then on the platform and caught up with fast and connect high speed train, just in train operation from the afterbody compartment exchange of train passenger up and down.But the short-distance train that subway is a type generally is controlled within half a minute at the platform berthing time, thus one save land the iron compartment each side the car door of four on-board and off-board is often arranged so that can be in the short time exchange passenger up and down.Obviously be these class methods iron class short-distance trains inappositely.Another kind of like patent CN94110534.2 (platform train and passenger train synchronous motion type railway station); Be characterized in that each all is provided with a circular turned railway in the Railway station on the way, passenger about the exchange during high speed train and platform train are turn-taked side by side on this circular turned railway.Obviously high speed train must slow down the speed of a motor vehicle, could in the circular turned railway, move, could with platform train back exchange passenger up and down side by side, but the speed of a motor vehicle slows down and is equivalent to want the loss portion of time.Certainly, if do the diameter of circular turned railway very big, high speed train also can be turn-taked in the circular turned railway with not derailing, but in very big circular turned railway, turn-takes, still in the loss time.This all runs counter to the original intention of quick railway transport of passengers.Above-mentioned patent still is not suitable on the short distance platform, particularly subway passenger's quick passenger traffic.
