Fine Track Straight (Top) compared to Kato Unitrack.

Is this Tomix compared to Kato track?

Yes. The top is Fine Track, the bottom is Unitrack. Both have Japanese (3 1/2' narrow gauge) tie spacing. Unitrack is 25mm (~1") wide with the ballest, Fine Track is 18mm and is shorter to match. Both are code 80. The Fine Track is 280mm (~11") long and the Unitrack is 248mm (~3 3/4").

Thanks for responding, temp. I've updated the description to make that more clear.
