About Aster Hobby USA LLC

Aster Hobby USA LLC was established in January 2002 as the exclusive Importer / Distributor for live steam locomotives and accessories manufactured by Aster Hobby Co. Inc. of Yokohama Japan. Our mission is to promote and sponsor the development of new US prototype locomotive models, marketing and sales of the entire Aster live steam spectrum as well as providing the best possible spare parts service. Since 1975, the name Aster has been known by Gauge One live steam locomotive enthusiasts and collectors alike. From the introduction of the British Aster "Schools Class" in 1975 to today's Union Pacific Railways FEF 3, the improvement in quality and complexity of Aster locomotives has never stooped and new challenging designs are continuing to inspire our imagination of the great steam locomotive era.

Aster live steam locomotives are available factory assembled and ready to operate, or as fully machined ready to be assembled kits. Depending on the type of locomotive, the complexity and number of individual components can vary from one hundred up to one thousand five hundred and as many or more hardware pieces. Kit assembly time can take from twenty hrs. to three hundred hours or more, depending on the type of locomotive and your level of skill. If you want to discover how a steam locomotive works and you have the curiosity and patience, an Aster kit may be your best choice. However if you desire instant gratification, a factory built version is available to you.

This website features only the most recent products available and provides updates on new locomotive projects in the design and production phase. Aster Hobby USA LLC also distributes trough a national network of authorized dealers.
