My requirements for the railway map illustration are as follows:

Style: A clean, modern style with a slightly stylized aesthetic. Think less "technical blueprint" and more "informative infographic." The color palette should be muted and sophisticated, perhaps incorporating shades of blues, greens, and grays, with accent colors used sparingly to highlight key features. Line weights should be varied to emphasize major lines versus smaller branches. Stations should be represented by easily identifiable icons, possibly incorporating subtle design elements reflecting the character of each station (e.g., a small building icon for a historic station, a modern icon for a newly built station). The overall style should aim for a balance between clarity and visual appeal.

Specific Locations: The map should cover the entire [Insert Name of City/Region Here] metropolitan area, including all major and minor railway lines. Specific locations to be included are: [List all relevant stations, including their precise geographical coordinates if available. If coordinates are unavailable, provide detailed addresses or descriptions of their location relative to other landmarks].

Key Features: The map must clearly display all railway lines, including their names and any relevant designations (e.g., express lines, commuter lines, etc.). Each station should be clearly labeled with its name. The map should also include:

• Legend: A clear and concise legend explaining all symbols and color-coding used on the map.
• Scale: A clearly visible scale bar indicating the distance represented on the map.
• Orientation: A north arrow to indicate direction.
• Points of Interest (POIs): Integration of key points of interest near stations, such as major landmarks, airports, or bus terminals. These POIs should be subtly integrated to avoid cluttering the map. Consider using smaller, less prominent icons for POIs than for stations.
• Transfer Points: Clear indication of transfer points between different railway lines, possibly using a distinct symbol or color-coding.
• Zoning: If applicable, subtle zoning information could be incorporated to provide context (e.g., different colored shading for different administrative districts).

Additional Elements:

• Interactive Elements (if applicable): If the output is intended for a digital format, consider the inclusion of interactive elements such as clickable stations that provide additional information (e.g., schedules, nearby amenities).
• Accessibility Considerations: The map should be designed with accessibility in mind, ensuring sufficient contrast between text and background, and using clear and legible fonts.
• Data Sources: A clear indication of the data sources used to create the map should be included (e.g., a citation or reference section).

The final illustration should be high-resolution and suitable for both print and digital use. The file should be provided in a commonly used vector format (e.g., SVG, AI) to allow for easy scaling and modification.
