Overview
Railway and metro stations are the urban circulatory system's nodes. This skill covers platform design, capacity modeling, interchange flow, accessibility, and the integration of stations with surrounding city fabric.
When to Use
- Designing railway or metro stations
- Planning platform-edge safety (screen doors, tactile paving)
- Modeling platform capacity for train frequency
- Designing accessible, step-free interchange routes
Key Principles
- Platform capacity — 0.5 sqm per standing passenger; design for peak 2-minute train frequency.
- Platform-edge safety — screen doors for high-frequency metro; tactile paving for all.
- Level boarding — platform height matched to train floor; gap < 50mm for wheelchair access.
- Interchange flow — transfer between lines < 3 minutes walking.
- Integration — station entrances connect to bus stops, bike parking, and pedestrian networks.
Process
- Define train frequency, passenger volume, and platform count.
- Size platform width and length for peak standing density.
- Design platform-edge safety (screen doors, tactile, barriers).
- Plan interchange routes between lines.
- Ensure level boarding and step-free access.
- Integrate with urban transit (bus, bike, pedestrian).
Common Pitfalls
- Platform too narrow — crowding at peak hours pushes passengers toward edge.
- No screen doors on metro — platform-edge accidents are preventable.
- Long interchange walks — passengers miss connections.
- Ignoring last-mile — station is useless without bus/bike/ped access.
Verification Checklist
- [ ] Platform sized for peak standing density
- [ ] Platform-edge safety measures included
- [ ] Level boarding with gap < 50mm
- [ ] Interchange walk < 3 minutes
- [ ] Urban transit integration planned
