Suburban Railway Networks – Indian Railway GK for RRB Exams
Quick Tagline for Exams: “Suburban = City + Satellite + 1500 V DC (old) / 25 kV AC (new) + 12-car rakes + 3-4 min peak frequency”
1. What is a Suburban Railway?
- Section of IR that provides urban rail commuter service
- Characterised by high station-density (≤2 km), high frequency (3–5 min peak), EMU stock, separate/parallel tracks to main line
- Also called Local, EMU, BEMU, MEMU services
