Getting to class on time is hindered by the congestion on the stairwells. For this reason, the stairwell between Rooms 2 and 4, (Johannesburg Station) is for walking up only. The stairwell between Rooms 7 and 8 (Cape Town Station) is for walking down only. Also, note that stairwells and landings are 'No-Stopping' zones. Let's all get to class on time!
