the Voith hydraulic transmission, driving the axles on the inner bogies. The bogies were Stork-manufactured RMO 9000 series, also used on the SM'90, and DD-IRM trains. The top speed was , reduced to when running in combination with the older (also diesel-hydraulic) Wadloper series trains. The combination of disk brakes and quiet operation results that the trains were often poorly detected by axle counters which are commonly found on the lines where the DM'90 operates. Train-protection is provided by ATB-NG. For cross-border operations out of Heerlen, three sets were equipped with the German PZB train protection system along with boarding steps to accommodate the lower platform height. Between 2008 and 2013, the sets operating between Zwolle and Kampen were provided with passenger information displays showing connection information in Zwolle, as tendered by the province of Overijssel. The trains were equipped with heating provided by both engine heat and, when necessary, additional electrical heaters. In depots, the heaters can be powered externally to avoid the need for operating the motors. Air conditioning is only present in the driver cab. Specific operations 3403 and 3410 were branded for the Zwolle - Kampen service. 3401, 3402, 3404, 3412 and 3414 were branded for the Apeldoorn - Zutphen service.
