Why this model matters

The 923 “Dr Yellow” Shinkansen is Japan’s famous high-speed inspection train, responsible for monitoring track conditions, signalling systems, and overhead lines on live Shinkansen routes. Its rare appearances on the network have made it a legendary model railway subject.

How to use it

Place the train on clean N gauge track and operate using a DC or DCC controller. Ensure smooth, level track for optimal high-speed performance. For DCC-ready versions, install a compatible decoder. Keep wheels and rails clean for reliable power pickup and smooth running.
