City Congress president Sanjay Nirupam visited CST and Churchgate stations in South Mumbai this evening as part of the drive.
He appealed to people to express their anger over the hardships caused by paucity of cash.
Earlier, Congress had organised a "note pe charcha" campaign to create awareness among the people.
"Demonetisation had helped black money hoarders to legalise their wealth while poor and law-abiding middle class are at the receiving end due to cash crunch," he said, adding the decision was implemented without proper planning.
