For transporting heavy bulk containers, the freight wagon leasing company AAE, now part of VTG, needed four-axle container wagons with a load capacity of 70 tons. With the existing 60-foot Sgns 60 units, the middle compartment would have had to be left empty when loaded with spoil skips. AAE had a sufficient number of wagons available for transporting standard containers, so the decision was made to shorten older Sgns 60 wagons and put them back into service as Sgmmns 173 wagons with a usable length of only 40 feet. AAE had more than 100 wagons converted in this way. The four-axle wagons can each accommodate one 40-foot and one 30-foot container, or two 20-foot containers. The new wagons were initially used in construction site logistics for the Stuttgart 21 project, when trains transported excavated material to places like Amsdorf in Saxony-Anhalt. Since several train sets were no longer needed for construction traffic, the short four-axle wagons are now used for transporting standard containers.
