CDG train to arrivals lounge

[Poppygirl]

I am travelling to CDG and I remember having to take a train to the arrivals lounge. I remember 2 sides to the platform, does anyone know what side I need to be. I am travelling alone and panicking a bit. Any help would be gratefully accepted. I have tried googling the information but it did not make any sense, talking about K L and M?

I'm sorry, I can't quite follow. What direction of travel do you mean? What is an arrivals lounge? Could you be more specific?
