One commuter, Anna Roberts, who works in Victoria, was stuck on a Brighton-to-London train well after 11am.
Speaking to the Guardian on Thursday, she said: "It's been nearly four hours now. Police and paramedics boarded our train because there is no air conditioning. They said they were bringing water but not enough for everyone to have one bottle each.
"Eventually we got water in plastic containers, which we are passing around the carriage. We were told that was all that was available. With the power off, it's like an oven in here. Police have said it's too dangerous to walk down the track."
A Network Rail spokesman said: "Getting people off the train on to tracks is not something we do lightly."
The company is still looking into the circumstances behind the incident.
