The key to the answer is that the speed of light is a limit only for an observer who is at rest with respect to the moving train. The train can go 1 trillion kps without breaking a speed limit. It can go as fast as its technology allows. However, an observer will not see the train exceed 300,000 kps. To "fix" the apparent contradiction, the train passenger's sense of time is distorted such that his or her clock runs slower than the observer's. For a better explanation I recommend the book "Understanding Einstein's Theories of Relativity: Man's New Perspective on the Cosmos," ISBN# 0486266591.
