Dutch railways mat '24 electric multiple unit

The New Zealand Railways Magazine also reported on developments on railways in other countries: here is a photo of the electric multiple units called mat '24, i.e. matériel from 1924, and nicknamed Blokkendoos (block box or set), used on Nederlandse Spoorwegen or Dutch Railways, which was electrifying major routes in 1.5 kV DC  at this time.

A preserved Blokkendoos power car with a couple of preserved carriages is shown below with an excursion train.
