This is the HO Scale GE C44-9W Union Pacific with Gunderson MAXI-IV Well Car from Kato.
Every hobby begins with a single step; start off on the right foot with a Kato UNITRACK Starter Set! Each starter set comes with a complete 4'x7' oval of track, a Kato Power Pack, a locomotive, rolling stock, a re-railer, and an instruction book on how to assemble and care for your new Starter Set. From then on, the sky's the limit thanks to UNITRACK's modular snap-track design. Build a complex basement layout, or keep it simple so that you can take it out in evenings; anything is possible with UNITRACK!
