France (Normandie) - Lines with Obscure or Sparse passenger services
Raccordement de Folligny: Bifurcation km 74,0 – Bifurcation km 74,9
[ERT 272, fiche Caen-St Lo-Coutances-Granville-Rennes] (ERA-E 27A1; ERA-R 69A4; S+W 26C2) FR23/150
This curve provides a direct connection between Coutances and Granville. Since 9 December 2018 all trains south of Coutances take this curve and call at Granville, rather than using the former route to Folligny which now has no service.
Raccordement de Serqueux: Sommery (Bif. des Bruyères) – Forges-les-Eaux (Bif. des Potiers)
[ERT 270, fiche Paris-Rouen-Le Havre] (ERA-R 70B5; S+W 14A1) FR23/151
This recently-completed curve allows trains to run directly between the Gisors and Rouen lines without having to reverse at Serqueux. Trains between Paris and Rouen may be diverted this way when there is engineering work on the main line. This is indicated by an extended journey time of about 2 hrs 30 mins.
Schedules indicate trains between Le Havre and Paris St. Lazare are diverted this way on Saturday afternoons and Sunday mornings on 1, 2, 15, 16, 22 & 23 April, 6, 7, 13 & 14 May, 3, 4, 24 & 25 June, 8 & 9 July and 12 & 13 August. Some trains on these days have an extended journey time of around 2 hrs 15 minutes but may still use this route. There are other weekends when trains are scheduled an extended journey time of between 1 hour 30 mins and 1 hour 45 mins. Those journey times have been observed for trains diverted between Mantes-la-Jolie, Conflans-Sainte-Honorine and Argenteuil and hence do not indicate use of this route.
