The Walthers Cornerstone HO Scale Northern Light and Power Substation is a must-have for adding authenticity to your electrical generation and distribution scenes. Substations are used to lower the current of high voltage before routing it to residential and commercial customers and can be found near generating stations, at large industries like steel mills and paper mills and as stand-alone facilities. This kit includes all the details of the prototype, from the transformers and steel framework to the chain-link fencing around the facility. Warning signs and billboard decals for the Cornerstone Basic Billboards frame kit are included.
