The Gare Montparnasse accident was a French railway accident that occurred on October 22, 1895, at the Gare de Paris-Montparnasse, during the arrival of express train No. 56, which served the Paris-Granville line. It caused one death and extensive material damage; its dramatic nature makes it one of the most famous railway accidents in the history of French railways.
On October 22, 1895, train number 56 departed Granville at 8:45 a.m. bound for Paris, where it was scheduled to arrive at 3:55 p.m. at platform 6 of Montparnasse station. The train was hauled by locomotive number 721, a type 120, engineered by Guillaume Pellerin and driven by Victor Garnier. Following the tender were two baggage cars, a mail car, and then ten passenger cars, including a saloon car, number 1506, occupied by the family of Albert Christophle, governor of the Crédit Foncier, and a final baggage car.

During its passage through Versailles-Chantiers, the train was seven minutes behind schedule. It recovered two of them as it approached the outskirts of Paris-Montparnasse, but despite its efforts, it failed to stop in time. Causing general panic as it entered the station at a speed of about 40 km/h, it pulverized the bumper, which consisted of three overlapping pieces of wood, then pierced the concrete median at the end of the tracks and the facade wall topped by a glass partition. Although slowed considerably by these successive obstacles, it crossed the small terrace overlooking the Place de Rennes and smashed through its balcony. Swept along by its momentum, the locomotive tipped over into the void, its front end plunging into the ground at the site of a tram stop, destroying a newsstand. The couplings resisting, the tender, which it dragged with it in the fall, remained suspended, clinging to the front car, which stayed with the rest of the train at track level. It is exactly 4:00 PM, as shown by the station's electric clocks, all stopped at the moment of the accident.

The photograph on the poster was taken shortly after the accident. The locomotive is literally hanging off the edge without the sleepers that were put in place two days later to support it. This photograph was taken right after the accident.
The name of the person who printed the poster is on the back, but unfortunately, it's barely legible.
For train lovers or anyone who wants a photo of such a special event, this is the opportunity.
