Chicago O'Hare Train System
 

Hello!

I was wondering if there is a way to go from a Terminal to another without having to go through Secruity again.

Thank you,

Paul

Which terminals are you talking about? You can move airside among 1, 2 and 3, but if you are going to 5 (Int'l) you will have to go through security again there.

I will be coming into Terminal Two so I wanted to move about the domestic terminals.

Thank you

Paul

As ms_go says, you can move (i.e. walk) among T1, 2 & 3 without leaving security. But the train is outside security.

You can definitely move among the three domestic terminals. There are walkways connecting all three - just follow the signs. No need to go outside security to take the train.

Thank you!
