Teleprinter Building
The communications hub
Bletchley Park’s communications hub in 1944 was in the Teleprinter Building and Huts 14 and 14A. On D-Day, just like every day, there would have been rows and rows of noisy teleprinter machines whirring, with dozens of staff running them.
There were over 60 teleprinters in this large building, along with others around the site. Bletchley Park was connected to the Y Stations (listening stations) and other sources where enemy messages were intercepted. The messages were then sent along the telephone lines to Bletchley Park for decryption.
The phone lines also carried intelligence out of Bletchley Park to their ‘customers’ in government and the armed forces. During D-Day the only direct links from Bletchley Park to overseas commands were by radio. But by the end of the war many telephone and teleprinter cables had been laid across the Channel, which meant Bletchley Park could communicate securely and directly with the Allied headquarters in France.
The War Office Signal Office in London with a section marked ‘Station X’, which is the name ‘customers’ knew for Bletchley Park.
A closer look at the Station X sign. Other signs include Melbourne, Italy and Cairo.

See a teleprinter on display in Block C opposite the café when you leave. It is an example of a Creed Mark 7B, the most commonly used British teleprinter during World War 2.
