Subway Train Interior Modern Aesthetic Walls

Create a design for a subway train interior with a modern aesthetic. The walls should be a sleek white with soft, ambient LED lighting along the ceiling. Replace the existing seating with curved, ergonomic benches in a gradient of teal to light blue. Utilize a different arrangement for overhead grip bars, opting for a minimalist, streamlined look. Remove any recognizable signage and replace it with simple icons for accessibility. Include large windows and a clean, grey flooring material to enhance the spacious feeling of the interior.
