The iconic Doctor Yellow, a brightly colored train that has patrolled the Shinkansen tracks for 24 years, arrived at Tokyo Station on Jan. 29, completing its final journey.

The T4 train, owned by Central Japan Railway Co. (JR Tokai), was responsible for inspecting railways, overhead wires and track signals prior to its retirement due to age.

The train's final run began on Jan. 28, when it departed from Tokyo Station for Hakata Station in Fukuoka. It traveled back to Tokyo the following day, inspecting the tracks along the way.

The train arrived at Tokyo Station in the late afternoon where it was greeted by a crowd of cheering fans.

"I’m so happy to see it," said a 6-year-old boy from Kawasaki, Kanagawa Prefecture. "I want to say thank you."

Seeing a Doctor Yellow train is a rare event and believed to bring good luck, as they run only once every 10 days and their schedules are never made public.

The train will be on display at the SCMAGLEV and Railway Park in Nagoya starting sometime around June.

Starting in February, the other Doctor Yellow train, T5, will be solely responsible for inspections. However, West Japan Railway Co. (JR West) plans to retire the T5 as early as 2027.

Afterward, JR companies plan to equip regular N700S series trains with inspection tools, which will patrol the tracks during their normal passenger services.
