The operators of the LUAS tram system in Dublin are being criticised for introducing higher fares at peak times.
From Monday, all rush-hour commuters using the trams will have to pay 10 cents extra for their ticket.
The higher fare will operate between 7.45am and 9.30am from Monday to Friday.
The LUAS operators say it is designed to alleviate rush hour congestion by encouraging people to use the service at different times.
However, Fine Gael TD Olivia Mitchell has accused the company of targeting its most loyal customers.
She says extra trams should be introduced to reduce rush-hour congestion instead of a penalty on people who use the LUAS.
