The Roco 6600133 is a four-axle Shimmns sliding tarpaulin wagon registered under SNCF and belonging to the Sogetank industrial leasing fleet. The dark blue sliding tarpaulin with white Sogetank logos covers a grey chassis with pad-printed UIC markings, load tables and a red parking brake handwheel. The overall finish captures the heavy logistics aesthetic that defines French Era VI freight rolling stock.
A four-axle Shimmns for modern freight consists
The Shimmns classification refers to a covered flat wagon on four axles designed to carry moisture-sensitive loads such as steel coil. The Roco model reproduces the PVC tarpaulin with raised vertical folds and tensioners, while the chassis features detailed air brake reservoirs, cylinders and brake rigging. The two independent Y25 bogies handle minimum radii of 358 mm smoothly, and the NEM 362 short elastic coupler keeps the buffers close together on straight track, opening naturally through points.
Confirmed technical data
The wagon measures 138 mm over buffers in HO scale (1:87), runs on Y25 bogies with low-friction axles and is fitted with a NEM 362 short elastic coupler. It is ready for 2-rail DC systems. Conversion to alternating current for Märklin layouts is possible using the optional Roco 40196 axle set, though that accessory is not included.
Layout integration and consist building
Within an Era VI freight train, the Shimmns Sogetank sits naturally alongside open freight wagons or tank cars. Its low profile and blue tarpaulin with well-defined corporate markings give the consist visual continuity without any element looking out of place. In a yard or industrial scene, this wagon helps the whole composition read convincingly as modern freight traffic.
