Yes, the photo is from the air train looking west.
Johnson Ave yard is in the background. The yard is numbered 1-4, North to South. The M7 is on track 1, M9 on track 2.
The track car is located on what will be Atlantic No. 4 track (tracks are being re-configured). Continuing east turns into track 12 in Jamaica. Those crossover switches just east of the track car, are west of Platform F (tracks 11/12) in Jamaica station.
