This is a Hornby OO gauge Stepney from the Thomas the Tank Engine series, released in the past. It is a powered locomotive. It can run on KATO HO Unitrack. The motor makes some noise, but it runs quite well. It's used, so it's slightly yellowed, and the box is as you can see, so I'm selling it at a considerable discount! - Manufacturer: Hornby, KATO - Model Name: Stepney - Colors: Yellow, Black, Red - Size: OO Gauge - Product: Thomas the Tank Engine Series - Number: 55 Thank you for looking. #ThomasTheTankEngine #ModelRailroad #HOgauge #OOgauge #Hornby #Bachmann #Kato
