Here you see a fancy passenger car from around 1875 from the McCord Museum. Everyone wore their finest clothes to travel by train then!
If you go by train now, you likely are familiar with the "cafe car", which is often no more than a small kitchen with some basics. In the late 1800s, however, many trains were outfitted with large kitchens and had full, five-star-level dining rooms and chefs on staff. Can you imagine?
As more and more people began to travel by train and more companies sprouted up to service them, accommodations began to shift to allow for lower ticket prices. This 1895 photo shows a standard "sleeping car" compartment where people would often sleep sitting up.
