 In 2003, Märklin introduced its first N gauge models under the well established Minitrix brand.A number of Märklin H0 scale three-rail AC locomotives have also been introduced in two-rail DC versions under the Trix logo and many models are shared between the two brands.Since around 2003 or 2004 Trix has made a two-rail version of the Märklin C-track, and the two are mostly identical except for the colour of the trackbed and the height of the rails (with Märklin being 2,3 mm high and Trix 2,1 mm).
