Working on my first N Gauge layout. Added the V4 set to what I already have, and I'm very happy with the set. The shorter turnouts are perfect for a switching yard, and they have changeable power routing settings. I was surprised to see the set comes with two turnout extension cords. I've read that these shorter Kato turnouts have had derailment problems in the past, but the two in my set work perfectly with my Kato F3, E5A, and FEF-3 locomotives and all my rolling stock. There's a lot in the box, and the extension cords make this a great value for the money.
