There should also be a handful of special models for the Dutch market. In prior years, there were assorted container cars (47051.001-004 (Samskip, P&O, VandenBosch), 47051 (Foodtrans) 47052 and 47053 (Den Hartogh) and other models.
Maerklin recently updated the Netherlands website to a Dutch version of the main Maerklin site. It does not have as much information about special models as the old site did.
