Omar is among the very few politicians who have supported the hike in train fares proposed by Trivedi in his maiden railway budget tabled in the Lok Sabha yesterday.
"We take populism to ridiculous levels. I genuinely believe people would happily accept the modest hike if safety and quality of service are better," the NC leader said.
"Populism will destroy the Indian railways. Then where will the 'aam aadmi' go?" he asked.
Omar had words of sympathy for Trivedi, wishing him well in whatever he does.
"What ever Dinesh bhai does, I wish him well. He's a good and decent person and we shared some laughs at the Kolkata book fair recently," he tweeted.
Omar also said Trivedi will be remembered for a long time due to turn of events following presentation of the Railway budget by him.
"Long after other railway ministers are forgotten Dinesh Trivedi will still be an answer to a general knowledge or entrance test question," he said.
Angered by Trivedi's proposal contained in the Railway Budget, Trinamool Congress chief Mamata Banerjee had written to the Prime Minister Manmohan Singh last night seeking his removal and replacement with minister of state for shipping Mukul Roy.
