Siemens Ltd (SIEMENS)
Rail Mobility division - e-locomotives, metro trainsets, bogie plant (Aurangabad)
Price
₹3,303
snapshot 30 Oct 2026
Strengths
Global rail-mobility technology leader with a dedicated India bogie-manufacturing plant (Aurangabad), giving it access to Siemens' global traction and signalling IP for Indian tenders
Risks
Rail Mobility is one of several segments alongside Smart Infrastructure and Digital Industries - segment-level rail economics are blended
Fiscal year (September-end) differs from Indian Railways' own budget cycle
Note: Fiscal year ends September: the FY22-FY25 columns hold Sep 2021-Sep 2024, and the 18-month period to Mar 2026 (after the Energy demerger) is left out; Mobility is one of several segments alongside Smart Infrastructure and Digital Industries

Where it fits
Draws power from the overhead electrification and converts it into the motive force that drives the wheels - pantograph, traction motors and power-electronic converters sit on the roof and underframe of the powered coaches.
Why it matters
Traction performance determines a train's acceleration, top speed and energy efficiency - the core technical differentiator of a modern electric trainset like Vande Bharat.
Where the value pool sits
Traction equipment carries some of the highest technology content and margin in the rolling-stock stack, with a handful of global majors and PSUs holding most of the qualified supply base.
Key drivers
Electrification of new and existing rail lines
Vande Bharat and metro rollout pace
Push for higher-speed, higher-efficiency traction technology
Replacement demand on the ageing electric-locomotive fleet
Potential bottlenecks
Small number of RDSO-qualified traction-equipment suppliers
Technology-transfer dependence on global majors for some power-electronics content
Long-lead procurement for traction motors and converters
Investor metrics to watch
Rail/traction segment order inflow, where disclosed
Margin differential versus the company's non-rail businesses
Qualification wins on new-generation trainset tenders
