Why this model matters
This kit allows expansion of an existing roundhouse by adding three additional stalls on a 10° centre, creating larger servicing facilities for scale locomotives. The detailed brickwork, interior textures, and structural elements help bring engine terminal scenes to life on HO layouts.
How to use it
Assemble the plastic kit on a clean work surface using appropriate plastic glue. Fit each piece accurately and apply paint and weathering for realism. Position the completed structure adjacent to a compatible roundhouse (sold separately) or within an engine terminal area to enhance layout visual interest. Store unused parts safely to maintain detail quality between modelling sessions.
