'Welcome to the Clifton Rocks Railway restoration project official site. The project is dedicated to restoring one of Bristol's hidden gems......'
Also a BBC studio in WWII ...
'Top Room: Transmitters Various transmitters were incorporated in this room. One served Bristol with programmes whilst two others were set up o keep the station in touch with the outside World in an extreme emergency. The largest transmitter was an American RCA 'H' group transmitter operating on 203.5 m and broadcasting the home service. This had been brought over from America on lend lease in the early days of the War. The other two consisted of a Harvey McNamara shortwave set, and an ex RAF medium wave transmitter for restoring communication between the other main provincial and metropolitan broadcasting stations should the Post Office telephone lines be damaged by enemy action.
Second Chamber Down: Studio This was equipped with piano, gramophone and other facilities for musical, dramatic or school's programmes and could take a cast of 10-15 actors. Poor acoustics were accommodated by installing heavy carpets and providing strategically placed quilting on the walls. Small scale musical, dramatic or feature programmes could be produced in this room.
The Third Chamber Down: Recording Room This room contained a Philips-Miller record and replay machine which used gelatine coated celluloid film 7mm wide, onto which recordings were cut with a sapphire stylus. Also within this room were sufficient programmes for many weeks of broadcasting.
Fourth Chamber Down: Control Room Here the BBC Engineers surpassed themselves in compressing an enormous amount of equipment into a very small space. The room incorporated switching gear for no fewer than 80 land lines leading to outside stations. The Post Office routed these in various formations to minimise the risk of a single bomb damaging all in one go.'
