KAT20210 N 310mm 12-3/16" Double 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)

Works fine for me so far.

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.

Has turned my small RRinto a viable two track main line

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.

Typical Kato quality. Solid & bullet proof

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!
