Mumbai Monorail Derails During Trial Run Amidst Safety Concerns
An empty train on a special elevated track, called a monorail, had an accident while it was being tested near its storage area in Mumbai.
The front part of the train came off the track when it was trying to switch to a different path.
Unfortunately, three workers on the train got hurt, but thankfully there were no passengers.
This happened during a test of a new, fancy warning system designed to help trains run safely.
The people running the monorail said it was a minor issue during a controlled test, meant to check how the system works in tough situations.
However, others pointed out that this kind of problem shouldn't happen with the new technology, especially since the monorail has had safety issues before.
The regular train service is still stopped for upgrades, and some people are protesting, wanting all monorail services to stop.
An empty monorail coach derailed and hit a beam during a test run outside Mumbai's Wadala depot.
Three monorail staff members, including the train captain, were injured and received hospital treatment.
The incident occurred during a test of new Communication-Based Train Control (CBTC) signaling technology due to a switch malfunction.
The operator, MMMOCL, described it as a minor incident during controlled safety trials, while injured staff and union members reported the injuries.
Regular monorail services remain suspended for system upgrades, and the accident has renewed safety concerns.
