Father kills himself and son on train line3/9/2011
A 41 year-old man and his six year old son were killed by a passing Intercidades train on 25 August at 11.15am at the Póvoa de Santa Iria station in Vila Franca de Xira.
The authorities who have been investigating the incident told the media they suspected the father committed suicide and killed his own son at the same time because of a split with his partner. The incident led to two tracks on the train line, which link Oporto and Lisbon, being closed until 1.30pm that same day.
