At least one Restore Passenger Rail activist has been protesting again while on bail for an earlier protest.

Four Restore Passenger Rail protesters glued themselves to Wellington's Adelaide Road this morning before police peeled them off.

Four people were charged on Monday after blocking the Terrace Tunnel.

Protester Rosemary Penwarden says they don't plan to pause protest action any time soon.

"I'm not going to stand by and let my grandchildren's future go down the gurgler."
