ENIGMA RAILWAY From the Cryptomuseum .com web site:
"During World War II (WII), the Germans used a special Enigma machine for the German Railway (Reichsbahn). It was a standard Enigma K with rewired rotors and a rewired UKW. Furthermore, the position of the turnover notches of rotors I and III were swapped . Enigma traffic from the German Reichsbahn was first encountered by the codebreakers at Bletchley Park on 25 July 1940 and all messages were decrypted until the traffic ceased a month later, on 27 August 1940.
According to internal BP reports, Colonel Tiltman was responsible for breaking Railway Enigma during this period. Early in the next year, on 23 January 1941, railway traffic was intercepted again, originating from Eastern Europe, Russia and the Balkans. Two weeks later, on 7 February 1941, the traffic was broken for the first time.
BP named the railway traffic key Rocket, but later renamed it to Rocket I."
This machine employs three rotors plus a reflector called the UKW (Umkehrwalze).
