The escalators on platforms 6/8 are the wrong way round, the one on platform 8 should go down and the one on platform 6 should go up. At present passengers going up the escalator walk right into the path of passengers coming from platforms 9-17.
If they were swapped passengers going up from platform 8 would be on the outside track avoiding passenger from 9-17 should could use the inside track, rather than having to cross over as the do now.
