I travel a lot for work, but most people go and take planes… Though truthfully, I hate flying because I get air sick. So, what I normally do is take trains across the country on contractor trips. However i go the upper class rate, because even though it costs more, it gives myself and others comfort on those week long journeys. The last train I took was this past summer season, and it was hotter than a furnace outside! I was truly thankful that the train had entirely fantastic quality air conditioning! I had one of those sleeper cars, and in the sleeper carriage it was even better than out in the correct area of the train. The air conditioning felt great. So great, I almost thought it was Fall or Winter! There was something about this air conditioning that was unusual from your general air conditioning you would have at home with a brand up-to-date and up-to-date heating and cooling system. This had a purified air kind of feel–you would assume that on a train, it would be murky. But not on this train it wasn’t! I was truly elated with this particular train corporation. Not every train I have been on in the past had top quality air conditioning that had a form of air purification going on with it. Who knows what kind of system they were running in there… All I do know, is I would like to be able to have an heating and A/C system like that for my house! I assume they have those A/Cs with the whole-house air purifiers, despite the fact that I don’t assume anything would compare to this. It must be some kind of commercial industrial heating and cooling system Again, who knows, despite the fact that I want one! I look forward to next time on this train.
