Just before 3pm, a unidentified passenger was robbed and thrown off the train at Goodwood station.
The man was not seriously injured.
Metrorail spokesperson Zino Mihi said: “We confirm that this incident was reported after 3pm [Tuesday] whereby a male commuter was robbed of a R35 and train ticket by two unknown males with knives.”
Commuters were also allegedly ambushed between Parow and Tygerberg stations by an armed gang.
In a post on the Metrorail Commuters-Cape Town Facebook page, a passenger wrote: “Cellphones and bags were stolen. Guns were involved and one guy had to jump off the train.”
However, Mihi said they had no record of this incident.
In another unconfirmed incident, commuters said Wednesday morning seven armed men robbed commuters just before Mutual Station.
She said they were however aware of cable thieves operating in that area.
“Our control centre indicated that there are people who are alleged to be digging cables in the area that rob commuters as well but we have no records of the incident,” Mihi said.
On Monday, commuters were robbed by armed men at Brackenfell Station.
And last Friday, between Eerste River and Lynedoch Stations, eight people were robbed, assaulted and thrown from the train resulting in one man dying of his injuries.
Meanwhile, the City of Cape Town is preparing to deploy 100 newly trained rail safety officers in November, Mayco member for transport and urban development, Brett Herron, said.
