Kato KAT20210 N 310mm 12-3/16" Double Crossover

It works very well. It added new maneuvering options to the layout. It is high-quality and worked perfectly. I used the factory settings; initially, I had a bit of trouble getting the electrical polarity right, but I soon figured it out, and everything went smoothly when integrating the new crossing into the rest of the layout's trackwork.

I did a two-track design with a standard 4x8 oval outer loop and an inner hour glass loop. This track is how I switch between the two and man it's a blast. You need an additional part, the Turnout Control Switch, in order to make it work. It's a shame it wasn't included, but it only costs another 7 bucks. Also, for the people who claim it details, you have to have feed power at all four sides of it. That means either by feeder track or by Terminal Unijoiners, before the track on the left and on the right. You do that, it's flawless. Doesn't matter where before it, it can be at the top of the track or at the sides, it just has to be powered all around it. I lean towards the Terminal Unijoiners because they don't require additional tracks (every time you use a feeder track, it requires a matching piece of track to keep the measurements the same). You definitely need this crossover!

Kato N unitrack is a quality product. Easy to set up and take apart if needed. Track with attached roadbed looks good also. Quality N scale track that is easy to use for beginners and experienced modelers. Double crossover makes it easy to run trains between inner / outer ovals.

Great product that makes switching between two tracks easier in a smaller amount of space. (Photo has Kato-248 next to double crossover for size reference)

Connected it to inner and outer loops and it works perfectly. Just plug and play, no mysterious tricks or instructions. Comes with extensive instructions that are easy to follow. Me? A real newbie but using Kato track has been a real breeze.

Typical Kato quality. Solid & bullet proof

Received what appears to be old or used product and expected new. Initiated return but it works so I cancelled return.

Great track for model railroad use. I using mine with T-trak with requires four feeders to work right. It is a bite expensive track part. I lucked out and it was on sale by 20% off but still expensive part to get. It works awesome and makes crossing over double mains in T-trak super easy.

Die perfekten Gleise für den Gelegenheitseisenbahner. Sie funktionieren ähnlich gut wie das Märklin C-Gleis System. Lassen sich gefühlt unendlich oft trennen und wieder zusammenstecken. Das perfekte Gleis für die Spur N. Die Weiche arbeitet sehr zuverlässig.

This product works as is should. Excellent value for money when you compare it to the peco equivalent which is twice the price.

Connected with M1 & V5 layouts. No complaints as this is a KATO product.

Works perfectly 👍🏻

ギミックに興味があり、購入してみました。 実際に動作させてみたのですが、大きさもさることながら、使うシチュエーションがあまり思いつかない ことに気付きました。エンドレスにした場合、内と外で逆向きにはしないですし、本製品の枕木は黒なので、高架線の複線スラブ軌道線路や複線フィーダー（コンクリート枕木で白）と繋ぐ場合は、チグハグ感 が出てします。でも、１つの切り替えで４つのポイントが変わるのは面白いです。
