Caroline Lucas has called for an 'Emergency Summit' between key stakeholders including Government, Southern Rail/ Govia Thameslink and Network Rail.
It follows another day of rail chaos effecting Streatham stations.
The Green Party MP is demanding an 'emergency response' to the train crises gripping Streatham and covering much of Southern England.
Yesterday there was serious overcrowding and people were stuck on trains for long periods in the baking heat.
The MP wants the Government to step in and call an urgent summit immediately.
Caroline Lucas MP said: “This is an emergency situation which requires an urgent response. I'm seriously worried that someone could be injured or worse. The Government must immediately call an emergency summit between all key stakeholders including Network Rail, the train company and Ministers”
“I’ve heard reports of passengers fainting and being stuck on sweltering trains on an extremely hot day. The failures yesterday were caused by a combination of problems with Network Rail, some of which were unavoidable, plus the usual delays on the service.
“I’m doing all I can to meet with the Minister responsible for trains later today to demand action to repair this failing service. Passengers have suffered for many months now and, with a new Government in place, it’s time for real action to address the multiple problems with this service. As a start the Minister should signal his intent by taking the service into public hands so Government can truly get a grip on it.”
