If you really meant, 'whilst travelling at", you could be quite right about the headlights, but the ball travelling "It travels at the same speed as it does when thrown when the carrige is stationary." still applies in motion at any speed, depending on the observer's viewport  Observed on the carriage, the ball would possibly be as you suggest, but, observed from outside (as a passerby) you get something different.

haha yes ok, very messy..
About the thrown ball, I didn't explain it well. Of course if a stationary observer could see inside a carridge going past at light speed. He would see everthing almost completely frozen in time with the ball hovering in mid air between the two peaple. So at no point would the actual ball be going FTL.
