A young mother killed herself and her two children by jumping into the path of a train, an inquest has found.
Mrs Sidhu and her children were killed on the tracks
Navjeet Sidhu, 27, jumped in front of the 100mph Heathrow Express train at Southall station, west London, in 2005.
Daughter Simran, five, and son Aman, who was 22 months old, were also killed. Six months on Mrs Sidhu's mother died at the same spot.
Coroner Alison Thompson recorded suicide verdicts for the women and said the children were unlawfully killed.
Mrs Sidhu and her daughter died instantly, while her son died in hospital two hours later.
All had suffered multiple injuries in the impact, on 30 August 2005.
In February 2006, Mrs Sidhu's mother Satwant Sodhi returned to the scene and stood in the path of a First Great Western train.
Her family said the deaths had left her "completely inconsolable".
"No matter how, as a family, we tried to help, she could not find comfort in anything or anyone," they said in a statement.
