KiYa 191 series

The KiYa 191 series was a Japanese non-revenue diesel multiple unit operated by the Japanese National Railways from 1974 to April 2008.
==History==
Designed to be able to conduct track or overhead line inspections on non-electrified lines or in lines where the overhead lines are not working, the six cars did exactly that for their entire service life. All cars were retired by 25 April 2008 due to obsolescence and were replaced by newer track inspection train sets.
One set was produced per year by Fuji Heavy Industries (now known as Subaru Corporation) from 1974 to 1976.

The KiYa 191's body style is based on that of the 183 series and later-style 485 series cars; this body style later formed the basis of what would become the 443 series. The KiYa 191 is painted in "Blue No.15" (ink blue) with "Yellow No.5" (marigold yellow) accents.
This color scheme of both ink blue and marigold yellow has been used on many non-revenue JR trains, including various tractor units like the 143 and 145 series.
==Specifications==
Construction was of steel. Each car was 21 meters long. The set uses a DML30HSF prime mover which has an output of 500 PS (493 HP, 368 kW) as used in the KiHa 181 series. Each set consisted of two cars permanently coupled together; one KiYa 190 and one KiYa 191 car. The KiYa 190 car was used to inspect overhead lines, while the KiYa 191 car was used to inspect signals.
