The global railway industry — carrying 12 billion passengers and 11 billion tonnes of freight per year on 1.5 million km of track — is one of the world's largest consumers of precision forgings per vehicle produced. A single freight locomotive (such as the GE ES44AC / Wabtec Evolution Series — 4,400 horsepower, 135-tonne operating weight) contains over 200 distinct forged components: axle sets (each weighing 1.5–2.5 tonnes per axle, 6 axles per locomotive = 9–15 tonnes of axle forgings per locomotive), wheel forgings (6 pairs per locomotive, each wheel weighing 400–500 kg), traction motor shaft forgings (6 per locomotive), gear case cover forgings, draw hook coupler body forgings, and bogie frame corner forgings. Indian Railways — the world's 4th largest railway network by route km (67,956 km total, 100,000+ km total track including sidings, 8 million passengers/day, 3.2 billion passengers/year — world's #1 by passenger-km) — is the world's largest single buyer of railway forgings, procuring approximately 100,000 pairs of wheel-axle sets per year for its fleet of 75,000+ wagons, 17,000+ coaches, and 13,000+ locomotives. Wabtec Corporation (Pittsburgh, USA — world's #1 freight locomotive and rail equipment OEM after merger with GE Transportation 2019, $10B revenue) supplies locomotives to Class I US railroads (BNSF, UP, CSX, NS), South African Transnet, Brazilian Vale, and Indian locomotive programmes.

The railway industry — often overlooked in forging market analysis compared to oil and gas — is in fact one of the world's largest and most technically demanding consumers of precision forgings per vehicle. A single EMU (Electric Multiple Unit) passenger train of 8 coaches contains: 32 axle sets (4 axles per bogie × 8 bogies × 2 bogies per coach = this math varies, but roughly 32 axles per 8-car EMU), each weighing 1.5–2.5 tonnes (solid axle forging EA4T steel, heat treated, UT and MT inspected per EN 13261), plus 64 monobloc wheel forgings (2 per axle, AAR Class C or EN 13262 ER8, hardness 260–290 HB, 300–450 kg each), 32 traction motor shaft forgings (in 34CrNiMo6, one per powered axle), and dozens of bogie frame connection forgings. For a 12-month Indian Railways production run of 500 Vande Bharat Express trainsets (India's domestic semi-high-speed EMU, 0–160 km/h, 16 coaches per trainset — total 8,000 coaches), the axle forging requirement alone is: 8,000 coaches × 2 bogies × 2 axles = 32,000 axle forgings. At 2 tonnes per axle forging, that's 64,000 tonnes of railway axle forgings per year — for this single train programme alone. Indian Railways' total annual forging procurement (across all axle types, wheel types, coupler bodies, and locomotive components) exceeds 200,000 tonnes per year — making it one of India's largest single institutional forging consumers. Shivam Forge supplies Indian Railways-specified forgings (RDSO-approved, IS 5517 Grade 30Ni4Cr1 axles, IS 1030 Grade 340-570W wheels) from its Rajkot facility, delivering to CLW (Chittaranjan Locomotive Works), BLW (Banaras Locomotive Works), ICF (Integral Coach Factory, Chennai), and RCF (Rail Coach Factory, Kapurthala) in 3–5 days by road.
Wabtec Corporation — formed by the 2019 merger of Wabtec (formerly Westinghouse Air Brake Company) and GE Transportation (General Electric's locomotive business) — is the world's undisputed #1 freight locomotive OEM. Wabtec's GE Evolution Series (ES44AC, ES44C4, ES44DC — 4,400 horsepower, 6-axle configuration, 135-tonne operating weight) is the dominant North American freight locomotive, with 10,000+ units in service on BNSF, Union Pacific, CSX, Norfolk Southern, and CN. Each ES44AC locomotive contains: 6 traction motor shaft forgings (34CrNiMo6, 120–180 mm OD, 700–900 mm length — for 6 × 725 HP AC traction motors), 12 monobloc wheel forgings (AAR Class B/C, 965 mm diameter, 450–500 kg each), 6 axle forgings (AAR M-102 Class B/C, 150 mm journal diameter, 2,100 mm between wheel seats), and 2 draft gear coupler body forgings (AAR M-211 Grade E, E-Type standard knuckle coupler — rated 1,500 kN). Wabtec also manufactures the T-LOC1000 and T-LOC locomotive for South African Transnet (143 units — South Africa's first locally assembled locomotives, $1B contract), Australian Pacific National (80 units), and Brazil's Vale Mining (100 units for iron ore operations). Shivam Forge's AAR M-1003 certified railway forgings — axles, wheels, couplers, and motor shafts — are supplied to Wabtec's Erie, PA (locomotive assembly) and Pittsburgh, PA (electronics) operations via CIF US East Coast ports in 22–26 days from Mundra.
Alstom (Saint-Ouen, Paris — world's #2 rail OEM after merger with Bombardier Transportation in 2021, €17.6B revenue, 75,000 employees across 64 countries) designs and manufactures the world's widest range of railway rolling stock: TGV/AGV very high speed trains (350 km/h, France/Italy), Pendolino tilting trains (250 km/h, UK/Poland/Czech Republic), TRAXX DC/AC/AC3 multi-system electric freight locomotives (Europe's most widely used freight locomotive, 2,500+ units in service on DB Cargo, PKP Cargo, SBB Cargo, Railion, and 50+ other freight operators), and Coradia Lint/Polyvalent diesel and hybrid regional trains. Alstom's forgings for TRAXX locomotives (bogie axle EA4T, traction motor shaft 34CrNiMo6, gear box pinion 18CrNiMo7-6) and Coradia EMU bogies are procured from certified European forge suppliers — but with Alstom's growing assembly in non-European markets (Alstom India: Sricity plant for Vande Metro, Alstom South Africa: PRASA trains), sourcing from Rajkot-based Shivam Forge offers significant cost and logistics advantages. Alstom India's Sricity (near Chennai) assembly of Indian Railway Vande Metro trains uses Alstom Coradia platform bogies — axle forgings in EA4T (EN 13261) or RDSO-equivalent IS 5517, delivered in 3 days by road from Rajkot.
Shivam Forge's railway forging competitive advantages: (1) RDSO approval — the critical barrier to entry for Indian Railways' 100,000 wheel-axle procurement per year; (2) Grade coverage — EA1N, EA4T (EN 13261 passenger axles), AAR M-102 Class B/C (North American freight axles), IS 5517 (Indian Railways), all in 34CrNiMo6 / 30Ni4Cr1 / C-Mn microalloyed steel; (3) Complete NDE — EN 10228-3 UT Class 3, EN 10228-4 MT, rotating bending fatigue endorsement for EA4T high-speed service; (4) Competitive pricing — 25–35% below European (Valdunes, Lucchini-RS, Bonatrans, GHH Radsatz) and North American (Simmons Machine Tool, Griffin Industries) forge suppliers on CIF destination; (5) Full OEM capability — traction motor shafts, gear pinion shafts, bogie bolsters, coupler bodies — covering the complete locomotive and rolling stock forging requirement from a single source. Domestic Indian Railways supply: direct from Rajkot to CLW Chittaranjan, ICF Chennai, RCF Kapurthala, BLW Varanasi — 3–5 days road delivery, open account trading terms with IR production units. International railway OEMs: CIF European ports (Rotterdam, Hamburg) 18–22 days, CIF US East Coast (Baltimore, Savannah) 22–26 days.
