The young German Federal Railways possessed in the early 1950s covered freight wagons, mainly outdated and long overdue for processing flat roof wagon G 10 and G 02. A complete overhaul economically made sense vs. construction and purchase of new cars which just was not in the budget. So the decision was made to the reconstruction and modernization of old cars: inter alia Base, springs and buffer length were transferred to UIC standard, the structure was also to UIC directives with - compared to the G 10 / G 02 - larger doors and vents. From the mid-1950s about 14,000 Gms were commissioned.From 1964 the cars ran under the name Gls 205. The drawn onto the wooden framework mounted in transforming PVC roofing was replaced in the 1970s gradually by a steel roof.
We have been coming up with something new: on some models the functioning taillight can be plugged when the carriage is used at the tailend. All models are finely detailed and feature doors with functional locking and individually opening vents. Prototypical models with steel roofs, a smaller step and no roof overhang.
