Another Toei 10-300 Series Train at Chitose-karasuyama No.4 Railroad Crossing 4

Light green is the line color of Toei Shinjuku Line. The old type of 10-300 series had a light green line under the windows, but the new model has it near the roof. Recent trains often have their line color near the roof so that it would not be hidden behind the platform doors at stations.
