The first 2x units of the series, units A 18-34 000 & 001, have modified bogies equipped with tilting technology but this technology is not retained for the other coaches of the series.

Like the entire rolling stock used for the Swiss Express service, these coaches are equipped with AK69 automatic couplings. / Sources: Voitures et fourgons CFF (1997), https://nl.wikipedia.org/wiki/SBB_EW_III
