Toll have two bank runs with metro's, departing BK approx 0630 and returning approx 1930-2000. The two ATR's (TOQ & TOX) only operate at night and arrive at BK approx 2300 and 0000 with a 90min turnaround. They also have a metro depart around 2130 each night. It's pretty impressive watching the ATR's punch out of BK's relatively short runway!
