With this, doubling of 145 KM Pune–Satara section is complete

Nagpur: Central Railway has successfully completed the doubling of the Shindawane–Ambale Ghat section, marking a major milestone in the ongoing Pune–Miraj doubling project. This 9.45 km stretch is widely regarded as the most challenging segment of the entire corridor due to its difficult terrain and complex engineering requirements. With this, the doubling of the important section of Pune – Satara is now complete. The Shindawane–Ambale section was commissioned following the inspection by the Commissioner of Railway Safety on 17.06.2025. With the completion of this section, a total of 258 km out of 279 km of the Pune–Miraj doubling project has now been commissioned. 

The completion of Shindawane – Ambale section posed several engineering and logistical challenges:

• 1 tunnel measuring 140 metres in length

• A ruling gradient of 1 in 100, requiring meticulous alignment and construction planning

• 1 critical viaduct bridge consisting of 13 spans of 30.5 metres each, with the tallest pier reaching 42 metres, completed within a single calendar year and designed for Long Welded Rail (LWR) compliance

• 5 major viaduct bridges featuring piers and abutments up to 18.3 metres high, with PSC and composite girders

• 30 lakh cubic metres of earthwork in embankment, with the highest bank reaching 35 metres

• 20 lakh cubic metres of earthwork in cutting, with a maximum depth of 25 metres

• 23 minor bridges spread across the section

• 16 sharp curves, including one with a 6-degree curvature

Overcoming geographical constraints, high embankments, deep cuttings, and major bridge works, this section stands as a testament to Central Railway’s commitment to timely and high-quality infrastructure execution. 

This doubling will help decongest the route, enhance punctuality, increase capacity, and facilitate the introduction of additional passenger and freight services.
