The line was opened in several sections as follows:[6] During the Second World War, the railway was heavily damaged by retreating German troops on the Gothic Line which made it unsuitable for railway services until 1954.

In 1999, the Faentina was entirely refurbished and the track from Borgo San Lorenzo to Florence was reopened via San Piero a Sieve, Vaglia and Fiesole.

Some of these trains make less stops for a faster service calling at Brisighella, Marradi, Ronta, Borgo San Lorenzo, San Piero a Sieve, Vaglia, Fiesole-Caldine and Firenze San Marco Vecchio.

There is also a daily regional train operating, except on Sundays and Public Holidays, between Ravenna and Firenze Santa Maria Novella calling at Godo, Russi, Granarolo Faentino, Faenza, Brisighella, Fognano, San Cassiano, San Martino in Gattara, Marradi, Biforco, Crespino del Lamone, Ronta, Borgo San Lorenzo, San Piero a Sieve, Vaglia, Fiesole-Caldine and Firenze San Marco Vecchio.

During the summer service, the line is also served by two Regional Trains between Firenze Santa Maria Novella and Rimini: During October Sundays there are special trains between Florence, Rimini, Faenza and Bologna to Marradi for the Sagra delle Castagne event.
