Commuters from Brighton and Hove need train companies to undergo a complete culture change, according to MPs.
The cross-party committee of MPs were critical of the way passengers were stranded or left without information during the ice and snow last winter.
And train companies falling short should face the threat of fines to make them raise their game, the MPs said.
They also called for the railway lines along the South Coast and between Brighton and Hove and London to be modernised in the long term.
They want the third rail system to be replaced with a more resilient form of electrification.
The criticisms and recommendations come in a report, published today (Thursday 12 May), by the House of Commons Transport Select Committee.
The report said that more could and should be done to ensure road, rail and air services continued to operate in ice and snow.
The report also said that the welfare of air and rail passenger must be taken more seriously and better real-time information must be provided to drivers.
The MPs said: “The rail industry needs to do far more to look after the interests of passengers during periods of disruption.
“Culture change is urgently required.
“The legacy of privatisation cannot be used to excuse the continuing inability of train companies to provide accurate information to passengers about delays and cancellations.
“Licence changes proposed by the ORR (Office of Rail Regulation) should be introduced as soon as possible and backed up by effective regulation. By next winter, there should be clarity within the industry about who is responsible for real-time information provision and customer-focused timetable systems should always display accurate information.
“Failures in information provision should cost the firms responsible money.”
Anthony Smith, chief executive of rail customer watchdog Passenger Focus, said: “Passengers will be pleased to see this report acknowledges many of the information failings that happened during the snow disruption in December.
“Failing to provide information at times of disruption is the number one cause of anger and upset on the part of passengers.”
The MPs’ report said: “Strategic salt arrangement introduced a year ago clearly kept many main roads open last December.
