When trains crash, how much does your train fare go up?

On Sunday, a freight train derailed in Sydney, leaving more than 30 people injured, and the NSW Transport Minister, Andrew Constance, said it had been caused by “poor design” and “poor maintenance”.

“It was a tragic accident and the people on board are obviously devastated,” Mr Constance said on Sunday.

“There are some really difficult questions to ask about why this happened, how can it happen and why it did.”
