bombardier有入標，新列車將現有東涌線設計改良，但因價錢問題投標失敗..
(得32卡車，交期又咁短，歐洲公司好蝕底，所以地鐵內部有微言呢單標明送俾Rotem) |

急住要車, 好多時係現有o既車款小作改良, 咁都幾好o既.
不過訂貨量真係少得可憐....訂多d, 其實都應該食得晒.... |

當然可以。此批列車車速將與現有東涌線列車一樣是135km/h（營運速度則130km/h）。 |

I don't understand
they use K train, not cheap, but the ride quality, comfort, external appearance much inferior to SP 1900...
SP 1900 uses lightweight aluminum alloy while K train uses stainless steel... twice as heavy and greater corrosion protection required...
Hope the new SCL will use Sp series
九鐵SP 1900一樣係用不鏽鋼黎做車身。
乘坐覺感係必須要用到大量加速計放係車身的不同位置黎作出有關計算，
另外，軌道幾何亦對乘坐感覺有重要的影響，單靠個人感覺係極不客觀的。#
(冇錯，我宜家的而且確係順手話埋西鐵試搭日果班毫無常識人士的"測試"方式。
其方式亦沒有任何科學方式的記錄，可以話係學術、交通迷界的羞恥！)
不鏽鋼車身的設計過程中必然要經過FEM方式去計算其安全性。
維修上，不鏽鋼與鋁合金車身的維修effort都已經係為節省工序為基。
係對任何才料做車身作出有關批評前，最好都係做定功課先好，唔係被人質詢之下就只會
現形……  |

If stainless steel is so good then why no one uses it on planes...
Although a bit out-of-topic, I would still like to remind you that all major airliners (Boeing and Airbus) that are flying currently DO USE stainless steel, it's just the matter of the percentage being used.

we all know that the traction system on K-trains, when the trains were first introduced, had huge problems with very abrupt accelartion, I think everyone knows that, the braking system were just as bad... this was before the systems were finetuned subsequently...
其實加減速的問題，這與K-Train本身沒有太大關係，只是當年地鐵輸入至列車的
行車程式並沒有加入調較乘客舒適度的因素。 |
