Bring your HO Scale steam- or diesel-era railroad to life with these ready-to-use accessories from SceneMaster! In the days before railroad radio was common, trackside phone boxes could be found at key locations along the tracks where crews might need to call the dispatcher. Relay cabinets provided secure and easy access to electronics controlling signals, grade crossing protection and more. Ready to install, this set is complete with three cabinets and four phone boxes.
