Kato 10-2259 Series 923-3000 Doctor Yellow 7 Cars Set (N scale)

The Series 923-3000 T5 Configuration, commonly called Doctor Yellow, is a Shinkansen inspection train that gathers baseline data for track and overhead-line maintenance on the Tokaido and Sanyo Shinkansen. Its distinctive yellow livery is popular with Shinkansen fans, children, and general travelers. The real train is scheduled to retire in January 2027.
