Doors Open, Doors Shut See A Picture

When the U2 arrived today I noted this door .An attempted  rushed shot failed. However between Theodor Heuss Platz and Bismarkstraße I realized the best way .Get off , camera at the ready .Blip doors open .Wait for the "zuruck bleiben" to be called and blip the doors closed .Easy .It may be Monday but I needed colour and whatever else the BVG gives this with it's bright yellow .Sunflowers with wheels all the year round .
