The turntable and the roundhouse are iconic railway structures, and at long last they are coming to the N Gauge Kato UNITRACK system! Featuring a modular design that allows the easy addition and movement of up to 36 tracks, a sophisticated dual-motor driven indexing system that guarantees proper alignment, and an easy to use Turntable power system that takes full advantage of the power routing functions of Kato UNITRACK so that you can move and park locomotives onto parking tracks or in a roundhouse with minimal additional wiring, the Kato N Gauge Modular Turntable is perfect for modelers looking to add something special to both their tabletop and their scenic layouts!

The Kato N Gauge Unitrack Turntable uses special fitted 10° track sections which can serve as powered parking tracks or can be substituted with dead end pieces. It's a "snap" to swap around and add additional tracks!

While the turntable is necessarily elevated because of the need for internal motors and other below-track equipment, thanks to clever engineering it is a mere 12mm (just under half an inch) from the base of the turntable to the top of the rails. By using the flexibility of Kato Unijoiners it is possible to connect the Turntable to a tabletop layout without the need to sink the turntable into foam.

Swapping or adding tracks is as easy as removing a screw - the modular design of the Unitrack Turntable is specifically tailored to allow modelers to easily change their Turntable layout without the need for any additional wiring or soldering - simply pop the screw cover off, unscrew the single screw holding the plate in place, and either exchange it for a blank section or one with tracks. The Turntable's indexing and power routing design will take care of the rest!

Here is the info on the turntable expansion pieces:

The turntable comes with 4 pieces of Straight Extension Track and 6 of the bumper track pieces.

20-284 are upgrade kits that can convert three Extension Track pieces into feeder track.  It is an optional part for advanced users as the turntable itself functions as a feeder as it rotates.  Can be used with the feeder control switches (24-850 and 851), and of course insulated Unijoiners, to allow advanced control of individual sections.

20-285 comes with 3 pieces of Straight Extension Track, as well as 3 pieces of bumper track.

20-286 comes with one each left and right Curved Extension Track pieces as well as some straight and curved Unitrack sections for expanding into the upcoming Engine Houses that will be made to go with the turntable.  We have no more info on the Engine Houses right currently.

24-850 are optional switches that allow one to power on and off individual sections of feeder track.  Will be a standard item and not only for use with the turntable.

24-851 are optional switches that switch the polarity of individual sections of feeder track.  They reverse the direction of the feeder they are connected to. Will be a standard item and not only for use with the turntable.
