Each platform must have a unique, consistent name
Summary: Use north/south, east/west, etc. — consistency over cleverness.
Each platform must have a unique, consistent name
Why this matters
“The train on the left” depends on which way you are facing. “Track 1” is good, but “Track 1 Northbound” is better.
Principle
Use absolute cardinals (North/South/East/West) or fixed IDs (Platform 1, Platform 2). Never rely on relative directions (“Inbound”, “City-bound”) unless they are universally understood in that specific closed system.
