First thank you to everyone that responded to my topic. I went back to ASMAD train status for arrival times from 1/2/16 - present, as per the info provided train # 97 was on time or early arrival 60 out of 251 times. Which to me is not very good, that's less than 25% of the time. As of train #98 that train was either early or on time 65 out or 255 times, again that's about 25% of the time. So I'm just trying to understand why these trains are late that much. Thanks again.
It depends on how you define on time. When I travel long distance I consider on time to be rather nebulous, up to an hour late or so is perfectly fine by me and I don't start getting antsy until about two hours late. In my experience having plans immediately after arrival from any form of transportation is asking for trouble, so when I travel I just plan on arriving sometime in the same time of day as when I'm scheduled to.
I did an ASMAD search and found that 97 was 2+ hours late 34 times this year into Miami, or 13% of the time, which seems consistent with my long distance train travel in general. I suppose depending on your point of view that may be acceptable or not, but those odds wouldn't give me second thoughts if I were planning on going to Florida.
