Unlike many other rapid transit systems, Chicago’s El has shorter railcars. They are only 48 feet long. The reason is that in the beginning, the system was owned and operated by private companies which, due to financial reasons, kept the land acquired for the tracks to a minimum. This resulted in some very sharp curves which normal length cars wouldn’t be able to clear. Since these tracks are still in use today and rebuilding the whole network to accommodate longer railcars is out of question the system is stuck to using these 48 ft cars.
