After removing the model from the spue and cutting out the middle section, I touched up the paint. The brown of the pole was close to Floquil rail brown and the green of the cross arm was close to an old bottle of Polly Scale paint I had around.
This is a very similar method I used on the Musashi-Koyama modules and that has worked out well.
The pole was painted a gray color with the colors of the cross arm, braces, and insulators being a close match to the TomyTec pole structures.
Musashi-Koyama modules line up just right with the Ntrak track spacing as shown here.
