[8] The RegioVan is a single-level, partly low-floor railcar for regional passenger service on less busy, mostly non-electrified railway lines.

In contrast to the previous designs of the Kolzam SN81 and SA104/122, the RegioVans have a modular lightweight body structure with a low floor in the entrance area.

[9] The units have double slide doors on both sides with a width of 1300 mm, located in the low floor area.
