The Night of the Trains (or Operation Party) was a sabotage operation, targeting the British railways in Palestine on November 1, 1945. The operation was one of the first carried out by the Jewish Resistance Movement, before its official establishment, and symbolized its founding. During the operation Palmach units sabotaged a network of railways around the country and blew up three British guard boats in Jaffa port and in Haifa, and a combined Irgun–Lehi unit attacked Lydda railway station, which is the key junction between the Haifa – El Kantara main line and the Jaffa–Jerusalem railway. An estimated 1,000 men were involved in the operations.
