On 28 July 2026 Indian Railways approved a ₹163 crore project to upgrade the electric traction on the Parbhani–Mudkhed double line (164 track km) in Nanded Division, South Central Railway.
Project Snapshot
- Sanctioned cost: ₹163 crore (approved 28 July 2026).
- Civil scope: Conversion of traction system and associated power-supply works over 164 track km.
- Administrative control: Nanded Division, South Central Railway (one of 18 zones).
Technical Features
- Conversion: Existing 1×25 kV single-phase system to a 2×25 kV autotransformer (AT) system.
- Key components: Overhead equipment (OHE), traction substations, feeders and autotransformers.
- Electrical effect: AT system preserves 25 kV contact voltage while providing ±25 kV feeder arrangement for improved voltage regulation and lower transmission losses over long sections.
Route and Operational Significance
- Location: Parbhani–Mudkhed lies on Highly Utilised Network Route‑9 linking Ajmer, Indore, Secunderabad and Dhone.
- Traffic mix: Carries both passenger and freight services; upgrade supports higher axle loads and denser train operations.
IASPOINT Booster Facts
- 2×25 kV AT system: Common on high‑density corridors to extend feeding length and reduce number of substations.
- Project delivery: Electrification and traction upgrades are implemented by zonal engineering units under the Ministry of Railways.
- Network planning: HUN classification guides prioritisation for capacity augmentation and freight throughput targets.
