Refurbished Corail coaches hauled by a BB15000 (broken nose design, solid pieces of machinery, with impressive reliability for 40+ year old locomotives, VMax 160 km/h) are the standard for direct Paris-Trouville-Deauville trains.
However, some of these trains may occasionally be hauled by BB26000s.
BB26000s (Vmax 200 km/h) are normally booked on Paris-Caen-Cherbourg services, but operational mishaps or changes happen. Yet, Paris-Trouville train paths are in the V160 category, which means that even if a BB26000 is used for traction, the max speed will remain at 160 even on the 25 km long section of track cleared for 200 km/h between Paris and Lisieux.
