本题考查对交通方式变迁原因的理解，需结合历史背景分析选项。关键点在于识别不同交通方式的竞争优势：便利性通常是用户选择的核心因素。铁路虽高效，但线路固定、覆盖有限；公交车灵活且能适应城市扩张，因此更受青睐。

选项分析

A. The buses were more convenient
公交车路线灵活，可覆盖铁路无法到达的区域，且班次更频繁，减少等待时间，直接提升便利性。

B. The railways closed all passenger services
表述绝对化，历史上铁路客运并未全面关闭，仅部分线路调整，非主要原因。

C. The buses were designed in a more comfortable way
舒适性因车型而异，且非用户选择的核心考量，次于便利性。

D. The railways stopped getting support from the government
政府政策可能间接影响，但题目未明确提及具体政策，且非直接原因。
