Kato N 20185 Unitrack Double Track Super-Elevated Curve 18-7/8"-17-5/8" 45-Degrees Concrete Ties (2)

Good

Great for doing a helix

The double track pieces are very robust. I recommend using as much as you can.

Had to cut these into two pieces because KATO does not make the track pieces needed to put two corner modules together using this super-elevated track.It would be nice if KATO could get their act together.

Perfect curved piece of double kato track
