On October 30, 1946, Feinstein participated in a raid on the Jerusalem railway station. The attack was one of a series of sabotage operations the Irgun carried out against the railways that day, as part of the Irgun's overall efforts to paralyze the British Mandatory government. The British had advance intelligence of the plan, and the operation was further compromised when the Irgun, not wanting to harm civilians in the station, published an advance warning. On the day of the raid, the British were waiting in ambush at the station. The Irgun raiders arrived in two taxis, and Feinstein drove the one carrying the bombs which were to be used - three suitcases filled with explosives. The team then rushed into the station, laid the three suitcase bombs, and put up a sign warning of mines. However, they came under British fire, and four of the attackers were hit, including Feinstein, whose left arm was shattered. Feinstein and some teammates rushed back to his taxi, and managed to escape. Despite his injury, Feinstein managed to drive the taxi, under a hail of British gunfire, away from the station using only one arm. After their escape, the British attempted to remove the suitcase bombs they had abandoned. When a police sapper tried to lift one of the bombs, it exploded, killing him and devastating the interior of the station.
