Wow, the answers are all over the place on this one.
It is the same difference as with aircraft when speaking of air speed, verses ground speed.
If walking at 4 MPH in the train you are riding, in the same dirsction of travel, YOU are moving at 4 MPH.
The train itself is moving 100 MPH.
Your speed, relative to the ground, will be 104 MPH,
If walking in the opposite direction of travel, your ground speed will be 96 MPH.

if you are walking in the same direction as the train is travelling you are travelling at 104 with respect to the surface of the earth , but like the other question you posted the only thing that is supposed to be absolute is the speed of light, everything else is relative, which is why he called in them the general and special theories of relativity

actually ... if you want to go 104 you must walk in the OTHER direction to get 100 MPH train PLUS 4 MPH walking to equal 104...

it depends, on what U use as Ur reference point, speed is all relative, from a point on the train Ur travelling at 4 mph, for a point on the track Ur travelling at 104mph, and from a train doing 100mph in the opposite direction Ur relative speed is 204mph.
it all depends oh what U use as a reference point

Relative to the outside world, if somebody watched you from the road through the trains window then you would appear to be going 104mph.
Relative to the inside of the train and its passengers you would only be going at 4mph.

Yes, if you are walking inside the train while it is traveling. Problem is - where can you find a 4 mile long train?

No!! if you walk backwards on the same train are you then travelling at 96 mph???

Relative to the surface of the earth, yes. The train is moving you at 100mph, and you are moving forward in it at 4 miles per hour.. But its all relative; the train is moving you, and you are inside it...

In relation to the ground yes,as you would find out if you stepped out the back of the train !
