457 series

The 457 series, and the similar 451, 453, 455, 471, 473 and 475 series, are Japanese dual-voltage electric multiple units operated by the Japanese National Railways and its various successors from October 1965 to March 2015.
==History==
Descended from the old 453 and 473 series types (which are practically identical apart from designations), the 457 series were introduced in 1965 and were originally used on limited express services but were relegated to local services by 1985.
JR East's 457 series sets were retired by 2008. The last remaining cars in service were retired on 14 March 2015 with the 2015 JR timetable revision. 
Additionally, some ex-457 series cars were inserted in between 413 series sets, either as cab cars or intermediate cars. These were retired in March 2021.
==Design==
The 457 series' body style is very similar to 113 and 115 series cars, although there are a few headlight variations.
==Specifications==
Construction is of steel. Each car was 20.5 meters long. Traction motors were resistor controlled, which was standard for the time.
