Where it fits
Provides the air-brake systems, couplers and onboard batteries/lighting that let a train stop safely and keep passengers comfortable between stations.
Why it matters
Braking performance is as safety-critical as signalling - it is the final, physical mechanism that actually stops the train that Kavach and signalling are designed to protect.
Where the value pool sits
Braking and auxiliary-systems suppliers typically serve rail as one segment within a broader industrial or auto-component portfolio, so margins and disclosure vary widely by company.
