As an EMT (though at the moment I'm not active), I have seen multiple instances when resuscitation was successful and many when it was not.

As a EMT maybe you can comment on my fear. Most People get trained, once, for emergency procedures. the when the need is there they panic fail to remember what they were taught x years ago. I would much prefer a active trained Medic to be available.

While you may be correct about individuals not going back to get retrained (I haven't seen statistics on this), I'll offer the following:
Typically, employers who implement AEDs in the workplace offer general training to employees once, but also offer reoccurring training to individuals in the organization that are responsible for responding to emergencies. This training usually involves having them maintain active CPR+AED training, which is routinely offered by the American Heart Association and the American Red Cross in practically every community in America. Individuals are certified for either 1 or 2 years and then they must attend a recertification session. I used to work for an airline, and our flight attendants were certified in CPR+AED and received regular retraining on a yearly basis. I assume Amtrak would do the same. As an EMT, I am certified in CPR yearly and am retested for my EMT certification every other year.
Secondly, CPR isn't that difficult to perform. Even if you forget the correct number of compressions and breaths, the CPR you do will still be effective, just not as effective as possible. Improper CPR is much better than no CPR at all. If you've dialed 911, all 911 dispatchers are trained in CPR and can instruct you what to do over the phone.
From an AED perspective, the device tells you what to do. So even if you forget the correct procedure, a voice actually walks you through it. Once you turn it on, it will tell you to "connect electrodes," then to place them on the chest (a picture is shown where they go), and to press the analyze button and stand back. If a shock is advised, it will tell you then to push the shock button and if not, it will instruct you to continue CPR.
Now, as far as your comment about wanting a trained medic, that obviously is desirable. However in a typical urban situation, you're looking at response times of 4-7 minutes at best for a 911 call (and in a rural situation, you'll talking about a lot more time). By the time you've reached the seven minute mark, you have an almost impossible chance of reviving a heart attack victim, especially if CPR hasn't been performed. If they are revived, chances are they will never regain full function. An AED allows you to respond to a situation very quickly, beginning treatment before trained personnel can arrive and dramatically increasing someone's chance of survival. Applying an AED cannot harm someone - they are specifically designed to never shock anyone with a pulse. Additionally, it doesn't make much sense to train Amtrak personnel as EMTs or paramedics. Really, you learn the necessary skills not just in the classroom but with lots of field experience. Even if Amtrak personnel were put through an EMT-B course, its much preferable to have trained, experienced responders on scene. Paramedics, in particular, can administer a wide range of medications to restart a stopped heart (which a defibrillator cannot do - contrary to popular belief - they simply correct
ventricular fibrillation). In order for paramedics to administer most of these medications, they need authorization from a doctor (otherwise known as 'medical control'). Every area has different protocols of what medications can and can't be used and which can simply be administered and which require authorization from medical control. Additionally, certification for EMTs is done on the state level. I hold licenses for CT and VT, for instance, but cannot be an EMT anywhere else.
So as far as Amtrak is concerned, having AEDs on board along with employees trained regularly in CPR+AED is the most practical solution, and its the solution that I've seen adopted in many areas of the transportation industry.
