Do Trains and Large Swaying Buildings Cause Earthquakes?

When 150-car Trains move across the surface of the Earth they create rumblings that in the middle of the night can be felt for 30-miles. Each train sends this vibrational energy both downward into the Earth and across its surface. If you ever go camping within 30-miles of a train when there is nothing else around you will feel this vibrational energy and if you are perfectly at rest then your body will slightly tense up and your pulse will increase as well.

Is it possible that large trains moving across or along Earthquake faults under the right conditions might trigger Earthquakes? Some believe they can but only under the right set of circumstances. Others say it is so nominal that it makes no difference. Yet, it is not nominal if it can be felt over 30-miles away.

Recently in Japan it was discovered that swaying buildings and the weight on or near a shifting fault line can cause an Earthquake. When asked about this some scientists said;
