Between Liberec, Turnov, Železný Brod, or Tanvald runs the Crystal Train of Arriva. The low-floor Desiro, which the carrier puts on passenger or express trains here, has been dressed up in a decent coat in the form of a polepiece, which refers to glassmaking traditions and invites visitors to glass museums, galleries, glassworks, workshops, art schools and other glassmaking places in the Liberec region. However, it did not stop at just the train's decal, the interior of the train was also dressed in the crystal legacy.

The crystal train was officially presented on 17 September 2021 at the railway station in Železný Brod.
