After you've added train tracks to your 15mm terrain collection, you might want to add a few railroad buildings.
The Train Yard Switching Tower from Gale Force Nine's Battlefield in a Box range is marked as suitable for use with Flames of War.
The tower would be part of a switching yard, where trains (and individual cars) are switched from track to track. In a typical wargaming layout, a switching yard might be represented a main line and a single side track (rather than multiple side tracks that would be over-scale, depending on the ruleset's ground scale).
The thin, shrinkwrapped cardboard box contains an expanded polystyrene foam container that holds the set's components.
The tower consists of three parts: first story, second story, and roof.
Bubblewrapped and packed inside two of the building sections are two buffer stops, intended to be placed at the end of side tracks.
The assembled building is four inches tall (to chimney top), about two-and-a-half inches wide, and one-and-seven-eighths inches deep.
The interior is almost one-and-a-half inches by two-and-one-eighth inches, large enough for a Flames of War medium base.
There were minor imperfections in our sample building. The roof piece was rough on one edge, with excess resin under the roof peaks and on the chimney, and one corner that is raised. The second story piece has a raised corner which does not sit flush with the lower piece, which mars the appearance but not the fit. The lower piece had a tiny bit of excess resin between the bricks on the back side.
Tactically, the building provides a second floor with unrestricted visibility, while the bottom floor has no windows and one door.
