For the trail of the Cambridge Museum of Technology, we've divided the spaces into eleven stops. Each stop is offered as a transcription (see below) illustrated for those who are not able-bodied to see the details of the site through descriptions and photography.  You can use the audio guide online or in situ which is provided freely here, stop by stop, starting with ENTRANCE YARD (CMT Trail stop 1) AUDIO.

CMT TRAIL STOP 1 WORDS SPOKEN BY CAMBRIDGE MUSEUM OF TECHNOLOGY'S CURATOR, PAM HALLS: The starting location is just outside the doors of Cambridge's Victorian sewage pumping station. Here we can see two cages and they were used to filter the sewage that came into the pumping station.  The idea was that you didn’t want to have anything big like wood or dead dogs snarling up the pumps, so these two cages, they would drop down into the flow of the stewerage about 40 foot below us and they had to be wound up twice a day and one of the workers here then had to pull out whatever was found inside there.  Within museum folklore there is a story that on one occasion they found a dead baby in there; very, very sad, it upset the workers no end.  So now shall we go into the building here?  You can see over the doorway it says 1894 which was the date that it was built.
