A husband has paid tribute to his "darling" wife and two small children who leapt to their deaths in front of a high speed train last Wednesday.
The photo of Mrs Sidhu and her children was taken two weeks ago
Manjit Sidhu said he was trying to cope with the loss of his partner Navjeet Sidhu, 27, their five-year-old daughter Simran and 23-month-old son Aman.
She jumped in front of a 100mph train at Southall station in west London.
Her husband arrived at the station but it was not clear whether he saw his wife jumping off the platform.
Mrs Sidhu, whose marriage was believed to have been in trouble, reportedly told neighbours just weeks before her death that she was four months pregnant.
"I am trying to cope with the tragic loss of my family whom I love so dearly," said Mr Sidhu.
"I miss them immensely and am in a lot of pain.
Police have released CCTV images in a bid to trace witnesses
"To my darling wife and kids, all I can say is that I love you with all my heart and I know that one day we will be together forever."
The Sidhu family said in a statement: "Navjeet was a loving daughter, good mother and adoring wife.
"Simran and Aman were beautiful, happy children and will forever live on in our hearts. Losing them will leave a void that will never be filled.
Police on Tuesday released CCTV images of Mrs Sidhu and her two children as they entered Southall station in a bid to trace witnesses to the incident.
The mother and her daughter died instantly when they stepped into the train's path. The little boy was taken to the nearby Ealing Hospital where he died later of his injuries.
Officers are planning to stage a special witness appeal at the station on Wednesday to help establish the exact movements of Mrs Sidhu and her children.
