Lézarde Express Régionale

The LER was a new fast service introduced in September 2001 to integrate this railway line into the Le Havre bus network and operated by the commune's council.

The line connecting Le Havre to Fécamp was opened in stages.

An extension was then built to Rolleville and opened on 14 August 1896 with the last section to Les Ifs (on the Le Havre to Fécamp line) on 24 December of the same year.

The frequency between Le Havre and Montivilliers was two return journeys every hour.

The frequency between Montivilliers and Rolleville however was restricted to only 5 return journeys daily.
