That was one big sumbitch.
The big one in Chicago carried over 2000 people at a time, but I can't find any source that gives the figure for this one.
Best I can do is count the cars (40?) and make a wild guess at their capacity (50? 100?) for as many as 4000.
I did find 4800 per hour at this delightful page:
