发帖数: 7856 | 1 北京地铁一二号线的3rd contact rail一般设置在列车运行方向的左边。所以在大分部
车站，供电的3rd contact rail总是在旅客所在的站台一侧，而且在站台上你看不到
3rd contact rail。我记得以前坐地铁，看到站台下面“有电危险”的警告，却总是看
不到那条供电的3rd contact rail。只有在一号线的八角游乐园，古城，苹果园三站，
由于站台在两边，所以能看到3rd contact rail。
纽约地铁的3rd contact rail确实大多是在远离旅客所在的站台一侧。
北京地铁电压为750伏，上海地铁采用架空接触网，电压为1500伏。感觉上海的更好些。 |

ActiveRecord实现了ORM的映射。
