Overview edit
On 27 October 2021, JR West announced its plans to introduce Japan's first route inspection train to utilize artificial intelligence (AI) on railway lines by 2025. AI is intended to be used by JR West as a means to cover labor shortages, which is a growing issue for the railway industry.[1]

The body and underframe are made of steel.[2] Each car is 21 metres (68 feet 11 inches) long[3] and 2.8 metres (9 feet 2 inches) wide.[2]
Livery edit
The DEC741 series carries a livery with a blue base and a yellow stripe, which makes the train more visible at night.[1]
Equipment edit
Each trainset is equipped with 64 cameras, 44 infrared lights for nighttime use, and a diamond-shaped pantograph to inspect overhead wires.
