..and just to reiterate that the east-west connectors are A39-B5 and C2-D40 (with B5-D40 and A39-C2 north-south connectors). There are NOT connectors between A6 and B39 or C39 and D6.

I add this point because there has been more than one occasion when I have arrived at the dead-end after C39 thinking I was in the A terminal and then had to walk back to C2 to crossover to the D terminal.
