The Roco 6600226 brings together two NACCO pool Shimmns sliding tarpaulin wagons in a single box. Individually registered under the Dutch NS administration, each unit carries its own distinct UIC number, avoiding duplicates on the layout and adding authenticity to the consist. The Epoch VI lettering includes technical panels, safety warnings in several languages and the NACCO leasing operator logos on the sides.
Wagons designed for steel coil transport
The Shimmns classification defines special flat wagons on bogies, optimised for heavy loads such as steel coils laid horizontally in internal cradles. The sliding side tarpaulin, reproduced in rigid plastic with three-dimensional folds and lower fastenings, simulates the real flexible fabric that protects the load in transit. This type of wagon is common on European industrial corridors linking steelworks with processing plants, and its presence on an Epoch VI layout sits naturally within any modern heavy freight scene.
Running gear and mechanics in HO scale
Each wagon runs on independent two-axle bogies with polished metal wheel profiles. The NEM 362 coupler incorporates a KK-Kinematik mechanism that keeps the buffers close together on straight track and opens up on curves to prevent collisions between units. The confirmed minimum radius is 358 mm, allowing integration into layouts with tight curves without compromising running performance. The insulated metal wheels are compatible with standard DC systems and can be converted for Märklin AC using the Roco 40196 axle set.
How they fit into a freight consist
With a total coupled length of 276 mm buffer to buffer, the set occupies a generous stretch of track and gives the impression of a long train even with few units. Two NACCO Shimmns wagons at the front or centre of an Epoch VI freight consist add variety of silhouette without breaking the coherence of the whole. Combined with open freight or tank wagons from the same period, the visual rhythm of the train gains naturalness and balance.
