Ghiembuphoa33 As Danhiel already mentioned above, the length of the inbound train and where you’re sitting in it will be the major contributing factor, not the platform number. So depending on your own walking pace, this might cause up to approx. 5 minutes difference.
Assuming you mean the lockers with “luggage room” (and not the travel centre, where queues have to be expected), getting to platforms 41/42 from there can be done in approx. 2-3 minutes.
Missing your train on 41/42 shouldn’t mean a major drama neither (unless we’re talking about the last connections around midnight), as depending on your destination, the next connection would follow within 3 and max. 30 minutes.
