QR offers free travel to trapped commuters

Queensland Rail will offer free travel for a week to commuters caught up in a network fault that left them trapped on a dark train for hours.

Passengers were forced to sit and wait, mostly in the dark, on Friday night as their train on the Ferny Grove line came to a standstill between stations.

Some resorted to urinating in the carriage.

QR blamed the fault on a flying fox that came into contact with overhead lines.

Deputy Premier and Trasnport Minister Jackie Trad on Monday said QR's response to the incident was not good enough.

"It was an unfortunate incident but absolutely Queensland Rail could have responded better with more accurate information," she said.

QR is encouraging everyone who was on the train to come forward to receive a written apology from the rail provider, as well as a week's worth of free trips.
