The 19th century Housatonic Railroad project is the one that has been his primary interest for some time, but he still enjoys all periods of railroading and is glad to have many friends who share that interest. He has tackled many disciplines in the hobby including layout design and construction, prototype-based operations, scratch-building of structures and railroad cars, molding and casting techniques, hand-laying track and switches and even some electrical and electronics projects. Craig loves to learn new things and expanding his horizons and skill sets helps keep the hobby fresh for him.
