Its reports stated that a detailed scrutiny of CCTV footage, witness statements, and train inspections confirmed that the coaches themselves were mechanically sound and that the trains operated within prescribed speed limits, around 72 kilometers per hour.Story continues below this adMoreover, adequate clearance between trains was established, negating any possibility of coach collisions.The CR report also highlighted the role of overcrowding, particularly on the Chhatrapati Shivaji Maharaj Terminus-bound train, as a significant factor that exacerbated the tragedy.The GRP investigation focused on potential lapses in core engineering and maintenance.The GRP probed officials responsible for prescribing the 105 kmph speed limit on the steep Mumbra curve, deciding the lateral distance between the two fast tracks, and the history of maintenance and repair work in the vicinity of the incident.Stay updated with the latest - Click here to follow us on Instagram© The Indian Express Pvt Ltd
