synchronized clocks with respect to rest frame

SR explicitly chickens out of any cases involving acceleration. As soon as the train started to accelerate, we were out of our depth. You can synchronise clocks when you're still or when you're moving, but you can't accelerate anything during the thought experiment unless you want to learn GR.
This is not correct. SR can handle acceleration just fine. All it cannot handle is gravitation.
