As a result, 'high-performance electric train-cars' that were superior in high-speed performance as well as in acceleration/deceleration performance were introduced one after another centered on major private railway companies in 1954 and later, accomplishing a big technical achievement. |
この結果、高速性能・加減速性能に優れ、しかも居住性の良い「新性能電車」が、1954年以降大手私鉄を中心に続々と出現して、大きな技術的成功を収めた。 |
