For PM rush hour, the Sheppard subway is scheduled every 5.5 minutes, while the Yonge subway is scheduled every 2.52 minutes. So you will have occasions when if everything is running as scheduled, you get three 6-car Yonge trains providing riders for a single 4-car Sheppard train.
Sheppard ridership remains atrocious ... and amazingly in the new
2013 subway ridership statistics that TTC released earlier this month, daily ridership on the line was down 2% from
last year! Interestingly, ridership was up at every station except Sheppard-Yonge and Don Mills. Don Mills ridership was down almost 6.5%.
I wonder if this drop in ridership is in relation to the new Finch East Express Bus from Finch station to Don Mills and Finch? Perhaps not, as all the lines were down except paradoxically the SRT. However the increase at all the stations except Don Mills is interesting.
