BN unit 62 (Line 51), Station Amsterdam Zuid. At this station line 51 changes from metro into sneltram. The collector shoes for third rail power supply have just been retracted. The pantographs are raised for use on the rest of the route to Amstelveen which is equiped with overhead wire. The folding boards, used to bridge the gap between train and platform on the metro section, will be folded down after leaving Station Zuid. The same proces is repeated the other way around for Amsterdam Centraal Station bound trains on line 51.
