DR, refrigerated wagon, "VEB Fischwerk Sassnitz", period IV

For traffic to Great Britain, freight wagons were acquired in the early thirties that corresponded to the smaller British clearance profile. They also had the suction air brake common in the UK.

From 1935 onwards, the DRG procured 50 refrigerated wagons in two lots in addition to covered wagons and stake wagons. The Gfkhs Saarbrücken type wagons had ice containers that could be filled through the doors above. The wagons were later given the type designation Tbnhs Berlin. Many of them were still around after World War II. Around 20 wagons came to the DB, some of them to the DR. The Deutsche Bundesbahn rented around half of the Tbnhs to the Transthermos company, the remaining wagons were used by the DB as Tbnhs 30.

After 1964, the new designation Icfrs 400 was planned for 19 cars. However, the imminent retirement was already foreseeable, and so it is not entirely certain how many cars were retired as Icfrs 400s in 1969.
