ED53型電力機車是日本鐵路的第一代干線客運電力機車車型，由日本國有鐵道的前身鐵道省于1926年（大正15年）從美國引進，適用于供電制式為1500伏直流電的電氣化鐵路，至1937年（昭和12年）被改造為貨運機車，改稱ED19型電力機車。
1922年（大正11年），日本鐵道省決定對東海道本線實施電氣化改造。由于當時日本并沒有制造干線電力機車的經驗，因此決定采用首先從國外引進的辦法，向美國的鮑爾溫機車廠和西屋電氣公司訂購了兩臺1000型電力機車，后來改稱為ED10型電力機車。1926年（大正15年），日本再次向鮑爾溫機車廠和西屋電氣公司訂購六臺干線客運用電力機車，當時定型為6010型電力機車（6010～6015）。1928年（昭和3年）10月，根據鐵道省的車輛形式稱號規程修訂，該型機車改稱為ED53型電力機車（ED53 1～ED53 6）。
保存于箕輪町民俗博物館的ED19 1號機車
ED53型電力機車投入運用初期，首先配屬到東京機關區，主要在東海道本線擔當旅客列車的牽引任務。1937年（昭和12年），仙山線作并至山寺區間全線開通運營，其中全長5,361米的仙山隧道是該線最困難的區段，最大限制坡度達到33‰，平均曲線半徑為200?300米。由于ED53型電力機車的軸重較輕，因此鐵道部門決定將ED53-3～ED53-6號機車轉往仙山線運用。為適應該區段氣候寒冷、坡度大的特點，由大宮工場對這四臺機車進行了改造，包括加大牽引齒輪傳動比、增加電阻器容量、提高各種裝置的耐寒耐雪性能等，經過改造的機車改稱為ED19型電力機車（ED19 1～ED19 4）。
