Historical information

These items were used by tram and bus drivers as part of the Metcard machine management system. The PM (portable memory) key was issued to each driver. At the start of a shift, the driver would put it into a cream-coloured terminal at the sign-on point (starter's office in the depot) and transfer their shift information onto the key. Once the driver reached the vehicle, they put the key into the black-coloured terminal (tram driver's keypad - TDKP or bus driver's keypad) to upload the shift data to the vehicle. See item 2582 for more details and other examples.
