Police said the girls, ages 3-7, were put on the train Monday by their father and told to sit there and he would return with their mother, but that never happened. Officials told Gulf News the girls know their parents' names but not where they live. A massive public outreach campaign was under way to find the parents, police said.
The children were found by passengers on an express train in Bihar.
Investigators suspect the girls were abandoned because many Indian families regard female children as a financial burden. Women who give birth to girls are often the subject of scorn or even torture. In India, many families demand a dowry in exchange for permitting a daughter to marry their son.
