Japanese train running sound and view in the car.(MIE/JR-Central/Series315-3000/TOSHIBA-VVVF) This is a scene of the new 315 series 3000 series C102 train belonging to JR Central Jinryou Car Depot. The main circuit system is a Toshiba hybrid SiC-VVVF with an integrated SIV, and the running sound is similar to the Meitetsu 9500 series and Nishitetsu 9000 series. ・4-car version with one-man operation in mind The 315 series, which began operating on the Chuo Line in March 2022, has been introducing 8-car 0 series trains so far. The plan is to introduce 23 8-car trains and 42 4-car trains, but at the end of 2022, the first 4-car version, C101 and C102, was introduced. This group is classified as the 3000 series, and the differences from the 0 series include the presence or absence of electric couplers and through-holes, as well as the installation of side cameras for one-man operation. On the Kansai Line, one-man operation is performed by two-car 313 series trains during the daytime, and four-car 313 series trains with a conductor on board are used in the morning and evening. The C102 train set has been put into service for this operation since June 1st. The line was unified with convertible cross-seat cars in the 2022 timetable revision, but this marks the return of long-seat car operation for the first time since the 211 series 5000 series. In this commercial operation, the aim is to accumulate boarding and disembarking images from side cameras and build a system to support one-man operation with AI, so will the line eventually be unified into one-man trains both during the day and in the morning and evening? The partner C101 train set is still undergoing test runs in the Shizuoka area as of June, and once the eight-car 0 series trains are in place, the four-car 3000 series trains will likely begin to be fully introduced. 02.JR Central / JR-CENTRAL • 02-1.JR Central (Nagoya area) / JR-CENTRAL Nagoya...
