KiwiRail DC 4444Wellington Wellington

4444 was originally built by General Motors Canada entering service in 1967 as DA 1526. It was rebuilt in 1979 as DC type (G22AR.) It was painted in MAXX livery with modifications for use on push pull trains for Auckland Transport. After reverting to KiwiRail it has been only the only ex lease DC to be overhauled and, to the delight of rail fans, repainted. In this long hood view we see original G12 features.

is it still able for operation? or just for show unit?

Definitely a work horse and in regular service on lower North Island lines. The class is gradually being withdrawn; many of the units leased to AT were rescued from dead line as it was.

this number is railfan's favourite, I saw on some youtube's videos...
