The assignments for this box were split up, main incident with smoke and people self evacuating was at 125 st. And St. Nicholas ave. The secondary incident was 2 full trains stuck near 135st. Station, units were directed there to assist in evacuating trains by using ladders to get people from express train on middle track to come down onto rails and then climb up into a train that was partially in station at 135 st. To get onto station and then walk up to street level, probably close to 1,000 people were stuck at this location on the trains because they stopped due to derailment, there was also an assignment sent to 100 st. Or so with similar issues. I think a rescue was at 125 and also another rescue at 135. Sq. 18 was up at 135 assisting in search and removal of people from trains
