Station spacing on the busiest lines and the only lines with service out side of rush hour is actually closer to 5 not 7km;
Lakeshore West - 55.7km / 11 stops = 5.1km per stop
Lakeshore East - 50.7km / 10 stops = 5.1km per stop
As for peak capacity, Metrolinx has stated that the system has capacity between 5,000-20,000 depending on the line in the peak hr & peak direction. The Richmond Hill line likely being the lowest and the Lakeshore West being the highest.
Specifically, the highest capacity on GO lines is seen between 8:05am at 8:33 am when 6 trains arrive at Union station off the Lakeshore West line. Seating capacity per coach is 162 people. Some trains are 10 cars while others are 12 cars long. A 10-car train will have a seating capacity of 1,620 and a 12 car train 1,944. I can assure having you having operated and walked through these trains with regularly that its standing room only in almost every coach by the time the train makes its last stop prior to Union. Considering that, 2,000 passengers per trains is a reasonable estimate although the actual numbers may even be higher, perhaps even approaching 2,500 per train. This equates to approx. 12,000 to 15,000 people arriving at Union from the Lakeshore West line in that 1/2 hour period. Which would of course equal 24,000 to 30,000 pph. Also the average speed of those 6 trains range from a high of 60kph to a low of 45kph. Top speed being 150kph.
However capacity is constrained by track space in the USRC where the other lines merge and by loading/unloading times at Union. Thus maintaining that level of service for a single line for more than a short period of time is difficult since without limiting the number of trains arriving at Union from the other lines. Which is why when you extend the period to one hour, the total number of trains only increases to 8 which equates to the total peak period total of 20,000pph. Fortunately work is underway to increase the capacity of the system within the USRC and at Union station itself.
