The Colorado & Great Western Modular Railroad Club is one of the largest HO scale modular railroad club in the Rocky Mountain region. Based in Westminster, Colorado started as an idea in 1998 by four HO scale model railroaders living in the Denver area, all were members of the Colorado Rail Link club at the time. The four were frustrated with the state of modular railroading locally. They felt that visual experience of modular railroading was missing continuity and a high-level of detail. They decided to start their own club and began planning the construction of modules that could be interconnected to form a large operating layout showcasing the visual continuity of modular displays with the operation they desired.
