Debated whether to post topic here or O gauge scenery forum.
Noticed there seems (to me) a dearth of wayside signal structures, that is signal cases or bungalows. I tried googling several different ways, but get lots of pages for buildings, crossing signals, wayside signals, telephone shanties, telephone poles, battery cases etc.
Plasticville made a nice looking signal case for crossings, but was part of larger package of "useless" extras, and Atlas makes a nice bungalow that conceal their signal boards. But when asked, neither company will sell those pieces outright. I am always on the lookout for the Plasticville case to add to my layout signal locations.
Modelers of course can knock these out "in minutes". I guess I have to assume that our crossings, interlockings and wayside signals operate by wireless magic
