A passenger on the Noarlunga 5.47pm train, who withheld her name, she they were travelling south when “just before Ascot station the Tonsley line train just carved across”.

“It was very scary seeing this train come towards you, we were going full speed until our driver honked their horn,” the woman said.

“People had their headphones on or reading books, (but) I was the second seat back, the man in front saw it as well it just mesmerises you, you stick to the chair and I don’t think you believe it.”

A Department of Transport, Energy and Infrastructure spokeswoman confirmed there had been an “operational incident” and TransAdelaide would investigate today.

“The train did not go on to the wrong line, there will be an internal investigation as to what occurred as part of standard procedure,” she said.

She said there were “minimal delays, 20 minutes to half an hour” before the driver was replaced “as a matter of protocol”. The passenger said: “They did apologise profusely, it could have been a disaster.”

The incident happened about 3pm yesterday on a city bound tram near Blackforest.

The driver approached a woman, 25, and told her not to consume alcohol on the tram.

A man, 20, who was with the woman then threatened the tram driver in what police described as “a very aggressive manner”.

The man was arrested and charged with aggravated assault. The woman was charged with giving a false name and address and breach of bail.

The pair will appear in court at a later date.
