The last time they did this GO recently, they had the go to 161 on it’s regular northbound track, then operate light to north of 167 middle track then come back down in service to 161 on the southbound platform and enter service there. It seems they don’t have use of that relay track this time around so the Northbound will enter 145 on the middle track, skip 155 and terminate at 161 on the southbound track, then go southbound in service from there.
