VIRM trains, full name Verlengd InterRegio Materieel (transl.

Lengthened interregional rolling stock), are a series of electric multiple unit (EMU) double-deck trains operated by Nederlandse Spoorwegen or NS (Dutch Railways), the principal railway operator in the Netherlands.

The VIRM trains evolved out of the previously existing DD-IRM series (DubbelDeks InterRegio Materieel or Double-deck interregional rolling stock).

The first batch of 81 VIRM trains was created by lengthening all the existing DD-IRM combinations by one or two railcars.

These sets differ in that they do not feature the catering lift, meaning the stairs could be wider and the destination screens inside the coaches have disappeared, where instead information screens with travel information have been fitted.

Starting in 2015, the VIRM-1 sets were being refurbished and fitted with new interiors similar to those seen in the DDZ trainsets, and with new-style liveries.

These include the instalment USB-outlets in both classes and the introduction of "love seats" on the balcony.
