PlayStation West Drayton Station

Am i missing something or is the far side platform with the missing route map inaccessible ?

 

Edit...just found some steps..duh

 

how did you get to platform 1 without crossing the line?

 

Had to cross the line m8. There is steps built into the front of platform. Look straight at the platform and you will see bricks sticking out of platform (below platform overhang) When you approach them the option to climb up comes up. Hope this helps
