The four persons died Monday while travelling from Agra the city of the Taj Mahal to Coimbatore in the country’s south.
Among those who died is a 81 year old.
Indian Railways spokesman Ajit Kumar Singh says “Heat seems to be a factor,”
“it is really unfortunate”.
“When the train was approaching Jhansi, we got a call from the on-board staff that one of the passengers is unconscious,” Singh said.
“We rushed medical staff to the station but they found that three of the passengers were already dead.”
“A fourth person died later in hospital.”
He explained further saying that a contributing factor that led to the deaths were because the deceased passengers’ were not in air-conditioned coaches.
Some part of India has been sweltering in temperatures that have risen above 50 degrees Celsius (122 Fahrenheit) .
