text: traveling faster? the 'equation' goes that one cannot travel faster than the object of which one is in.  but . .   if you're walking towards the front of the train while it's moving, aren't you actually moving faster than the object you're in? obviously if you walk in the same direction of the train in which you are, your speed seen from a person outside will be the sum of the train speed and you own speed related to the train. so you can travel faster than the train, at least for a while. maybe, what they are trying to say, is that you and the train will get to destiny at the same time, unless you get out of the train, so your avarage speed will be finally the same as the train if you start and end in the same place (for example, your seat).  a very differnt thing is when velocities are close to the speed of light. you cannot go faster than the speed of light, velocities don't sum without taking into account the relative times. but unless the train doesn't go at the speed of light, you can move a bit faster.
