 Each of Kingda Ka 's trains has an extra row of seat mounts . The panels could be removed for the installation of additional seats in the future . This modification would increase the capacity of each train from 18 to 20 , and the hourly capacity of the coaster from 1400 to 1600 riders per hour . Kingda Ka 's station is prepared for this modification , with entrance gates for the currently @-@ nonexistent row of seats .
