The family of a woman who jumped to her death with her two young children from a rail station platform is being given support by specialist police officers.
A reconstruction will be held at the station one week on
Navjeet Sidhu, 27, and her daughter, Simran, five, died instantly when they were struck by a Heathrow Express train in Southall, west London, on Wednesday.
Mrs Sidhu's 23-month-old son, Aman, died later in hospital.
A local religious leader said she was thought to be depressed but her employer has said she "seemed happy".
Hinmat Singh Sohi, of a Sikh Temple in Southall, said some of the Sikh community had said she was depressed, although he did not know the family personally.
Avtar Lit, chairman of the Asian radio station Sunrise Radio, where Mrs Sidhu worked as a receptionist for several years, paid tribute to her.
He said: "She had a perfect balance of a young lady who was born, or at least brought up in England: values, responsibility, intelligence, beauty.
"The kind of person where you think 'what a wonderful human being', the kind of person you want your daughter to be like."
Picture of movements
The family were at the station from about 1100 BST until 1320 BST on the day they died. Police said CCTV footage had revealed no significant new leads.
Results of post-mortem examinations carried out on Thursday have not yet been released.
British Transport Police will stage a reconstruction of the incident on Wednesday to help build a picture of Mrs Sidhu's exact movements in the run-up to her death.
Officers are also liaising with the Sikh community in Southall.
