Another collab, inititally built by me and then refined by BigDaedy and UrbanErwin I present to you:
the longest single-frame container car on european rails, the Sggnss 80!
Manufactured by Tatravagónka in the Czech Republic, these cars were designed to increase the amount of containers on a train, since the maximum lenght of a train is very limited in europe.

The car has space for four 20″ or two 40″ containers (or one 40″ plus two 20″) in different configurations.

Instructions for containers can be found here on Open L-Gauge as well!
