国铁于1986年4月17日发表了年度技术开发计划。主要课题有提高新干线、既有线的列车速度、改进运输体制、降低成本、治理新干线噪声以及磁浮铁路的开发。 1.提高新干线速度为实现山阳新干线260km/h化,开发信号安全系统;在东北新干线上,为达到260～270km/h的目标,11月将进行200系营业用车辆的走行试验。同时研制以300km/h为目标的无摇枕转向架,并进行性能确认和耐久试验。 2.提高既有线路的速度
National Railway in April 17, 1986 published an annual technology development plan. The main topics include improving the speed of the Shinkansen and existing trains, improving the transport system, reducing costs, managing the noise of the Shinkansen and the development of the Maglev Railway. 1. Improving the speed of Shinkansen In order to realize 260km / h of Sanyo Shinkansen, a signal safety system was developed. On the northeast Shinkansen, a running test of a 200 Series business vehicle will be conducted in November to reach the target of 260-270km / h. At the same time to develop 300km / h for the goal of bolsterless bolster, and to confirm the performance and durability test. 2. Improve the speed of existing lines
