14.(Eis)/KG 55 (Eis—"Eisenbahn", the anti train unit) remained the only independent unit of KG 55 to remain on bomber operations into 1945. It was officially formed at Dnepropetrovsk on 1 June 1943 using experienced crews from 9 "Staffel". It appears some of the unit personnel were in action earlier, as on 28 May an entry was made for the squadron's first loss on a bombing operation against Krapotkin train station in the northern Caucasus. The unit's main purpose was to use cannon-armed He 111s to attack locomotives.
