Le 30 septembre dernier \u00e0 Valserh\u00f4ne, a \u00e9t\u00e9 pr\u00e9sent\u00e9e l\u2019\u00e9tude commandit\u00e9e par l\u2019association LEX 2050 et son pr\u00e9sident-fondateur Alain Mayaud, aupr\u00e8s du bureau d\u2019ing\u00e9nieurs-conseils Citec, portant sur le prolongement du L\u00e9man Express dans l\u2019Ain, en direction de Culoz-B\u00e9on et de Nurieux-Volognat.
La commune de Seyssel Haute-Savoie, faisant partie des soutiens de cette \u00e9tude, \u00e9tait repr\u00e9sent\u00e9e par l’adjoint Florian Zuccalli, aux c\u00f4t\u00e9s des \u00e9lus des communes voisines de Corbonod et Seyssel Ain.<\/p>\n\n\n\n

Cette \u00e9tude met en \u00e9vidence la faisabilit\u00e9 de ces deux prolongements. Les travaux d\u2019am\u00e9nagement sont estim\u00e9s \u00e0 un peu plus de 36 M\u20ac, selon le sc\u00e9nario retenu. La desserte de Culoz pourrait \u00eatre assur\u00e9e au moyen du mat\u00e9riel roulant Alstom R\u00e9giolis, tandis que celle de Nurieux-Volognat serait possible avec le mat\u00e9riel Stadler Flirt. Il va de soi que la mise en \u0153uvre de ces prolongements ne pourra intervenir qu\u2019apr\u00e8s l\u2019entr\u00e9e en service des nouvelles rames du L\u00e9man Express sur les lignes les plus fr\u00e9quent\u00e9es du r\u00e9seau, permettant ainsi de lib\u00e9rer une partie du mat\u00e9riel actuellement en circulation.<\/p>\n\n\n\n

Ces deux prolongements pourraient \u00eatre r\u00e9alis\u00e9s sans porter atteinte \u00e0 l\u2019offre actuelle des TER et TGV empruntant les m\u00eames infrastructures.<\/p>\n\n\n\n

L\u2019axe vers Seyssel-Corbonod et Culoz b\u00e9n\u00e9ficie d\u00e9j\u00e0 d\u2019une desserte par les TER de la r\u00e9gion Auvergne\u2013Rh\u00f4ne-Alpes. Si un renforcement de l\u2019offre repr\u00e9sentait un atout, son apport demeurerait toutefois moins significatif que celui d\u2019un prolongement vers Nurieux-Volognat, aujourd\u2019hui d\u00e9pourvu de toute desserte.<\/p>\n\n\n\n

L\u2019association LEX 2050 pr\u00e9conise une mise en \u0153uvre par \u00e9tapes, \u00e0 partir de 2032\/2033, et jusqu\u2019\u00e0 la livraison de la nouvelle gare souterraine de Gen\u00e8ve, pr\u00e9vue pour 2038. Elle recommande \u00e9galement la r\u00e9alisation, d\u2019ici le milieu de la prochaine d\u00e9cennie, de travaux d\u2019am\u00e9nagement en gare de La Plaine, consistant en l\u2019ajout d\u2019un quai suppl\u00e9mentaire. Cette adaptation permettrait d\u2019assurer une desserte horaire vers Nurieux-Volognat et Culoz-B\u00e9on, d\u00e9cal\u00e9e de 30 minutes par rapport \u00e0 la premi\u00e8re, offrant ainsi une cadence de 30 minutes entre Valserh\u00f4ne et Gen\u00e8ve, puis \u00e0 terme un intervalle de 15 minutes entre Gen\u00e8ve et le centre de l\u2019agglom\u00e9ration gr\u00e2ce au prolongement de la nouvelle ligne RL7 jusqu\u2019\u00e0 La Plaine.<\/p>\n\n\n\n
