>>975859I'm pretty sure Japan of all countries wouldn't let any DMUs operate in a subway. That is the 103-1500 EMU in its original colors when the pass-through service initially happened in the 1980s when most of Chikuhi Line was electrified and the new Meinohama Station was built for the pass-through. Pic sort of related as this is the same set in later times after it was recolored into the JR Kyushu livery in 1995
Fun Fact: Initially the E17+E18 set seen was a full 6-car set, but it was modified along with 3 other sets in the late 1980s so it became a 3+3 car sets by adding control cabs in the former middle cars. However, those new "end cars" lack ATC so the separated sets need to the coupled back in order to enter the Fukuoka City subway lines.
t. JPN Wikipedia entry, and whole page is fucking long since it covered basically every variant of the 103 Series
