This news item I missed back in July, but it's interesting enough to post. JR East was already pegged to provide consultant services for the HS2 project in Great Britain, but on July 22 the firm revealed they had already started another service in addition to the previous announced items. This involved the use of their proprietary Hercules computer program to generate run curve diagrams. These run curve diagrams will be used to figure minimum running times between two designated points (stations) on the HS2 route. Presumably then hypothetical operating diagrams (schedules) can be generated using the data. One definition of a run curve: http://www.rtri.or.jp/eng/rd/seika/2003/02/lowcost_E08.html Details of the HS2 project: Top speed: 400km/h Top revenue service speed: 360km/h Train frequency- on completion of initial 1st segment (London-Birmingham): 14tph, on completion of second segment (Birmingham to Manchester and Leeds): 18tph Train length: 400m Details of the JR East project for HS2: Duration of simulation: June 10~Nov. 7, 2015 Test section to be used: Initial 1st segment (London Euston to Birmingham as well as connections to existing lines from Birmingham to Manchester/Leeds) Rolling stock to be used in simulation: JR East E5 and E6 Hypothetical HS2 trainset Stopping patterns: express type and stopping services Speed limits/standards to be utilized: JR East standard operating speed limits HS2 designated operating speed limits JR East press release: https://www.jreast.co.jp/press/2015/20150719.pdf Previous news from spring: http://www.railjournal.com/index.php/high-speed/hs2-appoints-jr-east-as-a-consultant.html
