Passengers on Yorkshire and Lincolnshire's railways have been hit with the largest fare rise in five years on the first working day of 2018.
Protests are planned at 40 stations in opposition to an average hike of 3.4% as it comes into effect on the first working day of the new year.
Labour claim fares have risen three times faster than wages since the Tories entered office as the dominant coalition power in 2010.
Protestors from the Green Party gathered at Sheffield Station this morning to voice their opposition to the plans.
The Campaign for Better Transport (CBT) has accused the Government of choosing to "snub rail passengers" by continuing to raise fares while fuel duty is frozen for a seventh consecutive year.
The price hike - the largest since 2013 - was determined by the Government using last July's Retail Prices Index measure of inflation to determine fares.
Bruce Williamson, of campaign group Railfuture, said "people are being priced out of getting to work" and called for for the Consumer Price Index inflation measure to be used for regulated fare increases.
The CPI is usually lower than the RPI, and is used by the Government to set increases in benefits and pensions.
