解锁陕北出行新方式 红色老区迈入高铁时代

Core Viewpoint - The opening of the Xi'an to Yan'an high-speed railway significantly reduces travel time from 2.5 hours to approximately 1 hour, enhancing connectivity in the region and catering to the travel needs of local residents [1]. Group 1: Travel Time and Train Operations - The Xi'an to Yan'an high-speed railway spans 299 kilometers and features varying travel times for different train services, with the fastest taking 68 minutes and the slowest 103 minutes, due to differences in stop strategies rather than train speeds [3]. - The time difference between train services is attributed to the number of stops each train makes, with faster services primarily stopping at key stations while slower services cater to more regional stops [3]. Group 2: Future Developments - The construction of the largest high-speed railway station in Western China, Xi'an East Station, is progressing, which is expected to further reduce travel time on the Xi'an to Yan'an route once completed [5]. Group 3: Train Classifications - The Xi'an to Yan'an high-speed railway operates trains designated with a "C" prefix, indicating they are intercity trains designed for high-frequency travel between adjacent cities, differing from the "G" and "D" classifications used for high-speed and regular trains, respectively [7][11]. - The "C" trains can operate at varying speeds depending on the track conditions, with some capable of reaching speeds of 300-350 km/h on high-speed lines, while others may operate at around 160 km/h on regular tracks [11].
