高鐵上為什麼沒有“E座”？網友：因為E在視力表上

“五一”假期臨近，不少人選擇乘坐高鐵出行。有些細心的旅客可能會發現，高鐵座位的編號是A、B、C、D、F，唯獨沒有E座，這究竟是為什麼呢？

掌握一些高鐵小常識，對您購買高鐵車票或許會有些幫助。

High-speed rail passengers may notice that seat labels include A, B, C, D, and F, but skip the letter E. This seating arrangement is influenced by the international convention used in airplanes.

高鐵列車上，二等座採取“3+2”座椅排列，3個座位一側用A、B、C表示，2個座位一側用D、F表示。

Seat arrangements vary by class on a high-speed train. Second class features a "3+2" arrangement, with A, B, C on one side and D, F on the other.

一等座通常採用“2+2” 式排列，從左到右依次是A、C、D、F。A和F靠窗，C和D靠過道，沒有中間座位。

First class has a "2+2" layout, labeled A, C, D, and F.

商務座通常採用“2+1” 或“1+1”式排列，從左到右依次是A、C、F或A、F，A和F靠窗，C靠過道。

The business class uses a "2+1" or "1+1" configuration, with seats labeled A, C, F or A, F, with A and F by the window and C by the aisle.

可以看到，無論是一、二等座還是商務座，都沒有E座，這也引發了網友們的熱烈討論：“因為E不發音”、“因為E在視力表上”、“因為E容易和數字1讀音混淆”……

還有網友幽默地表示：“E人”坐哪裡，哪裡就是“E座”。

為何高鐵沒有E座？

那高鐵上到底為什麼沒有E座呢？這得從飛機艙位說起。

早期飛機多是單通道，每排6個座椅，分別是 A、B、C、D、E、F。其中：

A、F是靠窗座位（window seat）；

C、D是靠過道座位（aisle seat）；

B、E是中間座位（middle seat）。

時間一長，A-F這六個字母就形成了特定的國際慣例：即A/F即為靠窗，C/D即為靠過道。

This seating arrangement is influenced by the international convention used in airplanes, according to the China State Railway Group.

On early single-aisle aircraft, each row typically had six seats labeled A, B, C, D, E, and F. Seats A and F were by the windows, B and E were middle seats, and C and D were aisle seats. Over time, these labels became standard to indicate window, aisle, and middle seats.

高鐵為了和國際接軌，就延續了這種國際慣例。但高鐵一排最多5個座位，要保留靠窗或靠過道的特定字母，便從大的字母開始刪減，所以高鐵就沒有E座。
