The U.S. focused on their highway network instead of public transport after WWII, unlike Germany and Japan. Nowadays, passenger trains use tracks that were used on old railroads. Some places such as the Portal Bridge in NJ require trains to go slow, and is a major choke point on the line.

Why do people go so slow over train tracks?
Is it better to go fast or slow over railroad tracks?
It may be smoother when you go over faster…but they are really taxing the shocks/struts and suspension more. Slower is better for the vehicle.
Should you drive slow over train tracks?
While crossing a railroad (or a speed bump), you need to slow down, mainly to negotiate the uneven surface. Essentially, you take your foot off the accelerator and put it on the brake pedal.
