As an observer, within the carriage, it would appear that there is just one chap throwing a ball to another chap.
There "relativity" was born
A similar thing can be seen with a carousel and two people at opposite sides throwing a ball to each other. To a viewer on the Carousel, the ball appears to go straight, but, when viewed from above, the ball travels in a curve. (corioli effect)
The Fourth dimension is time and us 3 dimensional criters see the shadow of that as "inside/ outside" (but it is both at the same instant - no beginning, no end)

Nope, sorry. Doesn't work like that. For one, as you approach the speed of light your mass becomes infinite. Time will adjust so that the speed of light is never exceeded.
If you are talking relative to another object, sure. a light beam going one way compared to a light beam traveling the other will add up to twice the speed of light but the point is neither in themselves will exceed it. You cannot throw the ball any faster than the speed of light in your example.
The experimental evidence for this is already out there.
