Bachmann Industries (Bachmann Brothers, Inc.) is a Bermuda registered Chinese owned company, globally headquartered in Hong Kong; specialising in model railroading.
Founded in Philadelphia, Pennsylvania, the home of its North American headquarters, Bachmann is today part of the Kader group, whose model products are made at a Chinese Government joint-venture plant in Dongguan, China. Bachmann's brand is the largest seller, in terms of volume, of model trains in the world.
In the past, Bachmann specialized in entry level train sets. In 1988, the Spectrum line of high-quality, detailed models was introduced to cater to more experienced hobbyists. In the past few years, Bachmann has retooled most of its product line, increasing the quality of its standard line products and discontinuing most of the Spectrum line.
Many of the Spectrum products have been slightly modified and are now sold as higher-quality standard line models. Bachmann produces models in H0 scale, N scale (1:160 and 1:148), On30, 00 gauge, HOn30 (H0 scale on N tracks) and G scale.
