Get an HO scale railroad running in minutes with the Kato 3-105 Unitrack HM1 Basic Oval Track Set with Power Pack SX. This complete, ready-to-run starter set pairs Kato's rock-solid Unitrack with a Kato Power Pack SX controller — just add a locomotive and cars and you're operating. The set builds a basic oval from 26-3/8" (670mm) radius curves and includes a rerailer section that makes placing equipment on the rails effortless.
Kato Unitrack's integrated roadbed, nickel-silver rail, and snap-together UniJoiners deliver reliable electrical connectivity and prototypical looks straight out of the box. The included UniJoiners even work with N and HO scale, plus other manufacturers' TT and HOn3 track.
Does this set include a locomotive?
No — the 3-105 provides the track oval and power pack. Add your favorite HO locomotive and rolling stock to start running.
Is the Power Pack SX DCC?
The Power Pack SX is a DC (analog) controller and is perfect for DC operation. For DCC, simply substitute a DCC command station.
Can I expand the oval later?
Absolutely. Kato Unitrack is fully modular — add curves, straights, turnouts, and Variation sets to grow your layout.
