Paris - Chatelet Les Halles (RER) Platform Views 2014 08 11

Watching trains at the platforms at Chatelet Les Halles. This is a major meeting between RER A, RER B and RER D. This is one of the largest underground interchanges in the world.

If those of you who give dislikes for the video could leave a comment telling me what I could improve in the video that would be really helpful. =)
