The Stadler multiple unit, popular in operating service thanks to its modular design, represented a rail vehicle highly sought after by many model railroaders from the very beginning. PIKO responded to this customer demand and developed both the GTW 2/6 and the GTW 2/8 as H0 models. PIKO attached great importance to the precise reproduction of the futuristic appearance, whereby the head shapes of the different multiple unit variants, which differ from each other in their external appearance, were consistently recreated. Prototypical model railroaders should appreciate the separately and positively inserted windows, the numerous, fine engravings, the highly detailed reproduced bogies as well as the precisely constructed roof pantographs (on the electric variants).
