NHK on "Doctor Yellow", the shinkansen maintenance train said to bring good luck to anyone lucky enough to chance upon one: their schedules are a well-kept secret. I saw it once in Musashi-Kosugi Sta. but wasn't fast enough to take a picture.

awww that's a cute little modern superstition.

It is the train which is loved by all though it is the vehicle for exclusive use of the examination for track.

That's a beauty of a wristwatch! I've given up on watches ages ago, otherwise I might be tempted.

A dream come true for train enthusiasts: a ride on Doctor Yellow, JR's Shinkansen track-testing trains.

It will be a rare treat for visitors considering that even the operation schedules for such trains are not normally disclosed to the public. Sightings of the trains are said to bring good luck. Next week, a lucky group of passengers will be allowed to board Doctor Yellow. JR Tokai's Doctor Yellow is based on the 700 Series Shinkansen, East Japan Railway Co. (JR East) operates the East i, which is based on the E3 Series Shinkansen.

JR Tokai will allow paid visitors to board Doctor Yellow on 22 and 23 March. Doctor Yellow will make one inbound journey and one outbound journey between Tokyo Station and Shin-Osaka Station each day. This will be the first time for Doctor Yellow to run with passengers since JR Tokai was created through the division and privatization of Japanese National Railways in 1987. Passengers will be able to see test equipment onboard and the "observation dome," a room on the train's roof that inspects overhead wires while Doctor Yellow is running. The ticket price is 23,620 JPY (USD176), or around 9,000 JPY more than the Nozomi Shinkansen ticket price for the journey between Tokyo Station and Shin-Osaka Station. The tickets are limited to adults, and 50 passengers will be able to experience the test train for each journey, meaning a total of 200 lucky train aficionados. JR Tokai received about 100 times more applications than available tickets on its website over five days from 24 February.

"Doctor Yellow," Japan's famous track-testing bullet train, will be retired in January. Plans for farewell events that will allow fans to thank the bright yellow Shinkansen for keeping the country's high-speed services safe were also revealed.

Here's a sneak peek into Doctor Yellow's interior. JR Tokai will phase them out next January, while JR West will continue to use them until 2027.



The Asahi article also features fascinating photos and a walk-through video.

Here's more news on phasing out the two remaining Doctor Yellow trains: the two trains, T4 (owned by JR Central) and T5 (owned by JR West) editions, have travelled without passengers along the Tokaido and Sanyo Shinkansen lines spanning Tokyo to Hakata Station in Fukuoka. The T4 will cease operations in January, while the T5 is set to retire after 2027.

JR Central said it will retire the ageing train in June. It started operations in 2001, and there are no plans for a successor. Instead, passenger-carrying N700S bullet trains will be outfitted from 2027 with testing and observation equipment to check tracks and overhead wires.



Sales of Doctor Yellow-themed toys and other merchandise also spiked ninefold in the week after the retirement was announced.

Yesterday, JR Central's iconic Dr Yellow had its final run.

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.

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

Japan's Most Beloved Shinkansen That the Public Couldn't Ride: "Thank You for the Happiness" – The Final Run of Doctor Yellow, the Shinkansen That Ensured Safety

Nicknamed the "Yellow Shinkansen of Happiness", Doctor Yellow has been cherished by many over the years. On January 29, JR Central's Doctor Yellow made its final journey, marking its retirement.

The train that took its last run had been in operation since 2001, conducting inspections of overhead wires and railway tracks.

The Tokaido Shinkansen, which opened just ten days before the 1964 Tokyo Olympics, has served as Japan's main transportation artery, carrying approximately 430,000 passengers per day. The iconic "dream super-express", with its white body and blue stripe, has maintained an impeccable safety record—there has never been a passenger fatality due to derailment or collision.

Contributing to this remarkable safety since the early days was Doctor Yellow. Officially named the Shinkansen Electric and Track Inspection Train, the train was affectionately nicknamed by former Japan National Railways (JNR) employees, and the name stuck.

Running approximately once every ten days, Doctor Yellow took two days to complete its inspections. However, its schedule was not publicly disclosed, making a sighting a rare and lucky event. This led to the belief that "seeing it brings happiness."

On January 29, Doctor Yellow departed from Hakata Station for its final journey to Tokyo. In Higashiomi City, Shiga Prefecture—between Kyoto and Maibara—a special photo exhibition was held in honor of its last run.

For over 20 years, Isao Nishimura, 72, has dedicated himself to photographing Doctor Yellow.

Isao Nishimura:
"Today is the last chance—there are no retakes. I want to capture this final run properly."

Over the years, Nishimura created and distributed his own timetables to help others catch a glimpse of Doctor Yellow. On this day, he joined fellow enthusiasts at a prime viewing spot to capture the train one last time.

Through the train's windows, the word "ありがとう" (Thank You) was displayed—allowing Nishimura to take a meaningful final shot.

Isao Nishimura:
"If I could say something to Doctor Yellow, it would be 'Thank you for the happiness.' Seeing so many people gather and feel moved—it's a happiness in itself."

The retiring train was one of two existing Doctor Yellow units, owned by JR Central. The remaining train, operated by JR West, is expected to be retired around 2027.
