Data from M. A Mallet, " The Development of the Compound System in Locomotives," The Railroad and Engineering Journal, Vol LXV, No 5 (May 1891), pp. 202-204.
The Compagnie de Chemins de Fer de l'Herault developed independently of the network encouraged by the Freycinet Plan adopted in 1878. Instead, local interests felt distinctly ignored by both the PLM and the Midi. A separate building project led to a line between Montpellier and Palavas being opened in 1872. Other segments followed, but the system was not well funded and long gaps between openings. Nevertheless, the Herault included 212 km (132 miles) of line at its peak in 1912.
