On Good Morning Britain, Shadow Transport Secretary Andy McDonald said: “We’ve got to invest in our transport infrastructure as a public service, not just an opportunity for people to take profits out of the system.”
Labour has also vowed to return the rail network to public ownership and prevent further franchising.
In response, Transport Secretary Chris Grayling said the rail companies were, in fact, losing money.
“Most of the big companies involved in the railways are struggling to make money. The reality is our railways are expensive to run,” he claimed.
He asserted the price hike was due to inflation as well as wage demands from the unions.
“People do need to understand the biggest upward pressure on fares does come from wage rises within the industry,” he said.
“The unions expect a higher wage rise than everyone else.”
The Transport Secretary promised a transformation of the national rail network over the course of 2019, with one his first moves to extend child railcards to 16-17 year olds, as well as starting a discounted railcard for 26-30 year olds.
