Amtrak and security check in procedures

What? Amtrak Security? What in the world is that? Does Amtrak check each passengers official government issued photo I.D.? Amtrak doesn't have a set procedure to check all passengers prior to boarding Amtrak or Acela trains. When the passengers board the trains, the conductor does a random check based on the passenger's ticket number series. Apparently it's a random check which they do on board the train. The reason they don't have a steadfast rule for checking in is because many of the Amtrak stations are unstaffed and there is no way to do things on a consistent basis. In the larger stations, there is a large police presence as well as bomb and drug sniffing dogs located throughout the stations. I was personally surprised by this. Guess it's been a while since I took the train and automatically assumed (tsk, tsk, tsk, must not do that they tell me) that security procedures had been heightened for Amtrak as well as the airlines since 9-11. FYI, Amtrak is owned and operated by the federal government. Go figure.
