To my Japanese students -
For those of you who asked me how to open manual train doors in England, here is your tutorial.
When the train stops at the station, wait for the `Door Unlocked` sign to light up, then pull down the window, reach for the OUTSIDE handle and push it down. Lean against the door to push it open but do not lean too far or you will fall out. Failing that ask a British person to do it for you.
Important Safety Tips: As the yellow sign says, check that the platform is there first.
About the red danger sign: It says that the emergency alarm is in the saloon. The saloon? I`ll get back to you on that one. In the mean time, stay put.
