It's true that we often don't take notice of the intricate details of things we see every day, especially those of the highly technical sort. Perhaps, it's just not in the purview of our interests. Have you ever noticed that there were different types of train railcars? Probably not, as we most often see only one type in our daily lives, if we use trains at all on our daily commute. But in this 15-minute video, Engineer Grady Hillhouse of Practical Engineering shows us the differences between every type of railcar and their respective design and functions.
A train is a simple thing at first glance: a locomotive (or several) pull a string of cars along a railroad. But not all those railcars are equal, and there are some fascinating details if you take minute to notice their differences.
