A major development for Austrian long-distance rail has been sighted at Stadler’s commissioning centre in Erlen. Georg Trüb states that this is the first Stadler SMILE (RABe 501) unit built for Westbahn. The train, believed to be RABe 501 042, is the first of three unit that Westbahn ordered earlier this year.
