We have installed a historical bell system on part of the ground covered by shed No. 1. With a form of Morse code, it was earlier the practice in railway operations centres to send messages generated by induction by cranking to announce the departure of trains from the neighbouring operations centre, such as a station. This method of notification died out in the early 20th century as the railway established its own telephone network. After this, the trains were notified by word of mouth.
