在 rails 这个 gem 里面，welcome/index.html.erb：

Processing by Rails::WelcomeController#index as HTML
  Rendered /Users/WuQi/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/railties-4.1.5/lib/rails/templates/rails/welcome/index.html.erb (2.0ms)

➜  cd /Users/WuQi/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/railties-4.1.5/lib/rails/templates/rails/welcome
➜  welcome  ls
index.html.erb

2 楼已经回答你了，Rails 默认有：

WelcomeController 新建 Rails 项目时，默认首页 index

MailersController 邮件预览的 index 和 preview 页面

InfoController 项目信息页面，包括：index、properties、routes
