4. Setup and Assembly
Assembly of the Kato 23-230 Viaduct Station Entrée (B) requires careful attention to detail. Follow these general steps:
4.1 Preparation
- Unpack all components and lay them out on a clean, well-lit workspace.
- Familiarize yourself with the parts by comparing them to the diagrams (if provided in the physical kit) or the product images.
- Gather necessary tools: hobby knife, fine-tip tweezers, plastic cement (for styrene models), and possibly small files or sandpaper.
4.2 Main Structure Assembly
Begin by assembling the primary structural elements. The viaduct station entrance typically consists of a base, support pillars, and upper platform sections.
- Carefully detach all parts from their sprues using a hobby knife or sprue cutters. Smooth any rough edges with a file or sandpaper.
- Identify the base plate and the main support walls. Apply a thin, even layer of plastic cement to the joining surfaces and press them together firmly. Hold in place until the adhesive sets.
- Attach any internal support beams or floor sections to the main structure, ensuring they are level and square.
- Assemble the upper platform section, which will sit atop the viaduct structure. This often includes the main station building facade and platform surface.

- Attach the window frames and glazing (if separate) to the designated openings. Use a minimal amount of glue to avoid smudging.
- Assemble and attach the staircases. Ensure they align correctly with the floor levels.
- Install any railings, signage, or other decorative elements according to the kit's design.
