Katsumi / KTM Electrics
Katsumi, also known as KTM, made these O-scale electrics in Japan during the 1960's. Though the electric locomotives on this page came equipped with scale wheel flanges, I have successfully operated them on both Lionel FasTrack and tubular track.
At this Wikipedia link is the Japan Railways electric locomotive numbering and classification system, which corresponds to the numbers on the four locomotives below.

The pantographs on this engine are KTM replacements. Originals may have been black.
