The '''Indian locomotive class WAG D-9''' is a class of 25 [[Volt|kV]] [[Alternating current|AC]] [[electric locomotive]]s developed by [[Siemens Mobility|Siemens]] for [[Indian Railways]]. The model name stands for [[5 ft 6 in gauge railway|broad gauge (W)]], AC Current (A), Goods traffic (G). With {{convert|9000|hp|kW|0|abbr=off}}, it will be the second most powerful freight locomotive in the [[Indian Railways]] after [[Indian locomotive class WAG-12|WAG-12]] along with WAG-9 HH. The first prototype was unveiled on 26 May 2025.<ref name="d9">{{Cite web |title=WAG D9 Locomotive on irfca catalog |url=https://www.irfca.org/apps/locos?search_term=D9 |website=irfca.org |access-date=2025-08-17}}</ref><ref>{{Cite web |date=2025-05-27 |title=Siemens made locomotive to be exported: Modi inaugurates 9,000 hp Made in India loco in Dahod |url=https://indianexpress.com/article/cities/ahmedabad/siemens-made-locomotive-to-be-exported-modi-inaugurates-9000-hp-made-in-india-loco-in-dahod-10030736/ |access-date=2025-05-27 |website=The Indian Express |language=en}}</ref><ref name="railwaygazette">{{Cite web |url=https://www.railwaygazette.com/traction-and-rolling-stock/modi-flags-off-indian-railways-wag-d9-electric-locomotive/68879.article |title=Modi flags off Indian Railways WAG D9 electric locomotive |date=2025-05-29 |access-date=2025-07-28 |publisher=[[Railway Gazette International]]}}</ref><br />
<br />
== Introduction ==<br />
The WAG D-9 [[locomotive]] is a "Heavy Haul" freight locomotive, conceived in response to the growth in rail freight, and the demand for powerful electric freight locomotives following the complete electrification of the Indian Railways network. At first [[WAG-9]] was introduced a long time ago now new locomotive had same color of [[WAP-5]] with [[Amrit Bharat Express]] livery.<ref name="railwaygazette" /><br />
<br />
In January 2023, Indian Railways placed an order with [[Siemens Mobility]] for 1,200 freight locomotives, each with a power output of {{convert|9000|hp|kW|0|abbr=off}}. It was the largest locomotive order ever for Siemens Mobility and the biggest order in Siemens India's history. The contract is valued at approximately ₹26000 crore (approx. $3 billion), excluding taxes and potential price adjustments.<ref>{{Cite web |last= |first= |date=16 January 2023 |title=Indian Railways places order for 9 000 hp electric freight locomotives |url=https://www.railwaygazette.com/traction-and-rolling-stock/indian-railways-places-order-for-9-000-hp-electric-freight-locomotives/63342.article |access-date=2026-03-09 |website=Railway Gazette International |language=en}}</ref><ref name=":2" /><br />
<br />
== Design and Testing ==<br />
The 1,676&nbsp;mm gauge Co'Co' locomotives, operating at 25 kV 50&nbsp;Hz, are designed to pull 4,500-ton loads at speeds of up to 120&nbsp;km/h along the [[Dedicated freight corridors in India|Dedicated Freight Corridors]] (DFCs).<ref name=":3">{{Cite web |last= |first= |date=16 April 2025 |title=Indian Railways unveils 9 000 hp electric locomotive |url=https://www.railwaygazette.com/traction-and-rolling-stock/indian-railways-unveils-9-000-hp-electric-locomotive/68658.article |access-date=2026-03-09 |website=Railway Gazette International |language=en}}</ref> They will feature advanced propulsion systems, manufactured locally at Siemens facilities in India. To ensure maximum efficiency and reliability, Siemens Mobility will utilize its Railigent platform for optimal performance and availability.<ref name=":0">{{Cite web |title=Siemens-Built Locomotives For Indian Railways |url=https://www.railvolution.net/news/siemens-built-locomotives-for-indian-railways |access-date=2025-03-17 |website=Railvolution |language=en}}</ref><br />
<br />
The locomotives will feature artificial intelligence into the locomotives to predict failures before they happen to bring availability up. They will also be equipped with [[Kavach (train protection system)|Kavach]] (Automatic Train Protection System). It also features an improved monitoring and diagnostic platform, and an advanced continuous real-time tracking through GPS.<ref name=":2">{{Cite web |title=Siemens Mobility awarded a €3 billion project in India – largest locomotive order in company history |url=https://press.siemens.com/global/en/pressrelease/siemens-mobility-awarded-eu3-billion-project-india-largest-locomotive-order-company |access-date=2025-02-24 |website=press.siemens.com |language=en|date=16 January 2023}}</ref><br />
<br />
This the first rolling stock in India to get certified under the stringent EN-14363 (UIC-518) (Criterion 4) for assessment of rolling stock dynamic behaviour. Trials were conducted by the [[Research Design and Standards Organisation]] (RDSO) and were completed in late 2025 on the Nagpur-Itarsi and Jodhpur sections. This will pull freight and non push-pull [[Amrit Bharat Express]] like livery match on locomotive yet later after speed trials<br />

== Manufacturing and maintenance ==<br />
The locomotives will be delivered over a span of eleven years, with the contract also covering full-service maintenance for 35 years.<ref name=":3" /><br />
<br />
Assembly will take place at the Indian Railways facility in [[Dahod]], [[Gujarat]], while maintenance will be carried out at four depots in [[Vishakhapatnam]], [[Raipur]], [[Kharagpur]], and [[Pune]]. Both assembly and maintenance will be conducted in collaboration with Indian Railways personnel.<ref name="railwaygazette" /><ref>{{Cite web |url=https://cmogujarat.gov.in/en/latest-news/pm-dedicated-9000-hp-locomotive-engine-dahod |title=PM Shri Narendra Modi to Dedicate Nation’s First 9000 HP Locomotive Engine at Dahod |date=2025-05-21 |access-date=2025-07-29 |website=cmogujarat.gov.in}}</ref><ref name=":1">{{Cite web |title=Siemens To Make Indias First 9000 HP Electric Loco For Indian Railways: Exclusive Interview |url=https://zeenews.india.com/railways/exclusive-interview-siemens-to-make-indias-first-9000-hp-electric-loco-for-indian-railways-2605514.html |access-date=2025-03-17 |website=Zee News |language=en}}</ref><br />

== Importance of the locomotive ==<br />
Indian Railways aims to reduce carbon emissions by over 450 million tonnes by maximizing the use of Dedicated Freight Corridors (DFCs) instead of road transport. The 9000 HP locomotives will enhance the efficiency of these corridors and support the Railways' sustainability goal of full [[Central Organisation for Railway Electrification|electrification]], adoption of [[Environmental technology|green technologies]], and sustainable practices.<ref name=":1" /> Additionally, this initiative will attempt to increase the railways' share of freight transport from the current 27% to 40-45%, supporting the government's logistics expansion plans.<ref name=":0" /> <br />
