Johannesburg Park Station

This is Johannesburg Park Station
The main bus and train station in Johannesburg.
Busses from neighboring countries and outlying towns.
Trains are not that common anymore but in times past I used this train station often.
Today i went to pick up a friend arriving from Bulawayo Zimbabwe.
What this station lacks is notice boards with information about which busses are arriving and leaving. It would help as there is mass confusion of people trying to find information.
