View of Seibu 001 Series and 6000 Series from Daiya Deck 6

My photostream has some photos of roof of Seibu 6000 series. They show ventilators on the roof, like “Seibu 6000 Series Train and Tokyu 8050 Series Train at Entrance of Underground Section.” The 6000 series in this photo has no ventilator on the roof. According to the internet, they were removed during renovations between 2014 and 2019.
