why does my apartment complex 'sway' at night when freight trains pass?

i live in a block of flats, 4th floor flats, low rise - next to a railway line..and at night i often hear freight trains passing through the night and when they go by, the apartment slightly wobbles or vibrates?

why is this?

    Trains are heavy and as they pass by, the ground is transmitting the vibrations through the building foundation. The height of the building is amplifying those vibrations.
