I photographed Tokyu 5050 Series train set numbered 5178F, the latest model of the 8-carriage 5050 series. It was manufactured in August 2019, making it the last train set produced during the Tokyu Corporation period. It started its regular service in February 2020 after the split of Tokyu Railways from Tokyu Railways.
Similar to the 5177F set manufactured in 2016, the exterior of the 5178F set features front skirts equipped with snow ploughs. The interior design resembles the 2020 series, but unlike the 5177F, the 5178F does not have headrests on the seats near the door pockets.
