Central Japan Railway Co. (JR Tokai) has developed a new test train to check for worn electric cables and warped shinkansen tracks.

The train, nicknamed “Doctor Yellow,” took three years to develop and is modeled after the 700-series bullet train, company officials said.

The seven-car train, painted yellow with a blue stripe, can run at a maximum speed of 270 kph, the fastest in the world for an inspection train, according to JR Tokai.

The train is not the first Doctor Yellow. The one currently in use was modeled after the first shinkansen and runs at a top speed of 210 kph, the carrier said.

The new Doctor Yellow has a wide array of state-of-the-art devices that dramatically increase the precision of the inspection, including a video monitor installed at the front to enable operators to get a better view of the tracks ahead.

Company officials said the new model will undergo testing until the summer before making actual runs on the Tokaido and Sanyo shinkansen lines, which connect Tokyo and Hakata in Fukuoka.
