Up for sale is a Trix HO Scale (22599) Union Pacific Class 4000 Big Boy #4015 steam locomotive and tender, equipped with factory-installed DCC Decoder The locomotive and tender are in excellent cosmetic condition with crisp details and complete handrails. Note on packaging: The original inner factory foam insert disintegrated over time (a common occurrence with these Trix/Märklin releases). The engine and tender were safely wrapped in a protective cloth inside the wooden presentation box. The interior of the wooden box and packaging have been thoroughly cleaned of any foam residue using isopropyl alcohol. Please view all high-resolution photos for exact cosmetic condition. If there are any more questions, as this is a high ticket item, do not hesitate to DM for more pics or info.
