Route Engineering Challenges

  • Split operation at Okayama (14-car train divides into two 7-car halves in ~5 minutes — complex coupling automation)

  • Overnight operation requires precise timing coordination with daytime JR freight + commuter traffic on the Tōkaidō Main Line

  • Navigates densely-used conventional lines alongside regular Shinkansen and commuter services without dedicated overnight track

  • Single-track San'in Main Line segments require precise meet-pass coordination at rural stations (Sunrise Izumo only)

  • Seto Ōhashi Bridge gauge-mismatch handling (combined road + rail bridge, 13.1 km, requires specialised track maintenance)

  • Limited shower facility requires pre-paid shower card distribution system (~120 cards per 7-car half)

  • Nobi Nobi carpeted bay requires strict fire-safety + hygiene protocols for overnight mixed-gender use

  • JR East / JR Central / JR West joint operation requires revenue-sharing coordination across three corporate entities
