CAPE TOWN - At least 29 people including 27 passengers were injured Thursday in a collision between two trains in South Africa's Eastern Cape province, the second of the kind in the country in one week.

The accident occurred at 1:45 pm local time at the East London railway station, where a train moved onto the wrong track to collide with another occupying that platform,  according to Metrorail.

This was a "light collision" in its "own yard", Metrorail's regional manager Richard Walker said.

The collision left 29 people injured, two of them staff members, he said.

The victims suffered slight injuries and were sent to local hospitals for treatment, Walker said, adding that an investigation has been launched to determine the cause of the accident.

Last Thursday, two passenger trains collided near Saulsville in Pretoria, injuring at least 200 people, some critically.

The train accidents have raised alarm for security in the country.
