J’emprunte la ligne d’Auch \u00e0 Toulouse, plus pr\u00e9cis\u00e9ment entre Pibrac et Saint-Agne<\/strong>. Cette ligne est parcourue par trois types de rames\u00a0<\/strong>:<\/p>\n

–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Des automotrices Bombardier, qui circulent par 3 ou 2 (voire seules\u00a0!)\u00a0.<\/p>\n

–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Des rames Bombardier (3 voitures entre lesquelles on peut se d\u00e9placer par un syst\u00e8me de sas), qui peuvent \u00eatre assembl\u00e9es par deux (i. e. 6 voitures). Les voitures me semblent un peu plus petites que les automotrices.<\/p>\n

–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Des rames Alsthom plus r\u00e9centes, mais moins bien am\u00e9nag\u00e9es, compos\u00e9es de 4 voitures. J’ai vu une fois deux rames assembl\u00e9es, mais c’\u00e9tait pour d\u00e9placer une rame en r\u00e9paration.<\/p>\n

Entre un assemblage de 2 rames Bombardier ou de deux automotrices, il y a donc une diff\u00e9rence de capacit\u00e9 \u00e9norme.<\/p>\n

Je constate ce que je consid\u00e8re comme un dysfonctionnement important. Je prends g\u00e9n\u00e9ralement \u00e0 l’aller le train de 8 h, ou celui de 7h30, et au retour ceux de 18 h 30. Tr\u00e8s g\u00e9n\u00e9ralement, elles se composent de 2 ou 3 automotrices Bombardier, rarement d’une rame Alstom ou Bombardier. Le matin, c’est l’heure de pointe, les rames sont bond\u00e9s, \u00e0 la limite du dangereux en cas de freinage brutal par exemple. Le soir c’est un peu mieux, les retours sont un peu plus \u00e9tal\u00e9s.<\/p>\n

Or, il m’est arriv\u00e9 de partir \u00e0 8 h 30 le matin ou 19 h 30 le soir. Il y a nettement moins de monde sur les quais. Malgr\u00e9 ce, j’ai alors tr\u00e8s r\u00e9guli\u00e8rement la surprise (qui n’en est finalement plus une) d’emprunter des doubles rames Bombardier, largement sous-\u00e9quip\u00e9es<\/strong>. Encore plus \u00e9tonnant, j’ai vu aussi passer (lorsqu’elles sont en retard) en direction d’Auch 8 h du matin de ces doubles rames Bombardier, quasiment vides<\/strong> \u00e9videmment.<\/p>\n

Et en plus de tout cela, il y a les trains \u00ab\u00a0exceptionnellement en capacit\u00e9 r\u00e9duite\u00a0<\/strong>\u00bb\u00a0; vu leur fr\u00e9quence, il semble que la SNCF ne conna\u00eet pas le sens de l’adverbe \u00ab\u00a0exceptionnellement\u00a0\u00bb…<\/p>\n

Je n’ai pas grand-chose \u00e0 dire de plus, si ce n’est qu’\u00e0 mes questions on a toujours r\u00e9pondu que l’optimisation de l’utilisation des mat\u00e9riels \u00e9taient une science trop complexe pour \u00eatre comprise par un profane, ce vis-\u00e0-vis de quoi je demeure sceptique<\/strong>.<\/p>\n

Ce probl\u00e8me est d’autant plus aigu que, de par les tron\u00e7ons \u00e0 une seule voie le long du trajet, un cadencement meilleur qu’1\/2 h n\u00e9cessiterait le doublement des voies notamment en pleine ville (peut-\u00eatre envisageable entre Brax et Colomiers, mais pas entre les Ar\u00e8nes et Saint-Agne), ce qui me para\u00eet difficilement envisageable. En termes de priorit\u00e9, dans le cas peut-\u00eatre particulier de cette ligne, je mettrais des rames plus longues d’abord<\/strong>, plut\u00f4t que de viser un s\u00e9quencement d’un 1\/4 d’heure qui\u00a0me para\u00eet\u00a0bien plus co\u00fbteux, et de long terme.<\/p>\n

Cordialement,<\/p>\n
