The Inside And Outside of The MRT

Today I went to the Paya Lobar MRT station.This MRT station is on the ground so I can clearly see the train come,slow and stop.I took the photo while it was slowing down.We can see what the people were doing inside at that moment .I think we can often see the moving train and the moving landscape while we are outside or in the train .But only the picture can catch the inside and out side at the same time.If I have a speed camera,The scene inside will become more clear and the photo will become more wonder.
