Overview
- Thane railway police registered an FIR against a senior section engineer and a section engineer after investigating the June 9 incident near Mumbra.
 - Police cite acts endangering life under the Bharatiya Nyaya Sanhita, with reports variously mentioning Section 25 or Sections 125(a) and 125(b).
 - The case stems from a collision-risk moment on a sharp curve between Diva and Mumbra where two overcrowded locals passed each other and footboard commuters fell after backpacks brushed.
 - Four passengers died and others were injured in the fall, and officials say further investigation is underway.
 - The action comes as wider scrutiny mounts over Mumbai suburban rail safety, including an activist’s call to reconcile large gaps between RPF and GRP fatality figures.
