On signal gantries spanning several tracks, separate signal posts (UK: dolls) are collected, each doll pertaining to a different track. In the days of mechanical signalling, only around 10 existed in Belgium; they were found at some larger stations. The ones in the pack are modeled after gantries found in Oostende in the 1950s.
The zip-file contains five gantries of different size, of which three are fixed-size assets and two are splines, a separate gantry pillar for intermediate support of a large spline gantry (not prototypical). The pack also contains various signals, primarily of the three-position system and including some with electric light units, and the library which is specific to these assets. Other dependencies can be found in the library folder.
