horizontal straight line. What does this tell you about
(a)
the train’s velocity,
(b) about its acceleration?​

when the velocity time graph for the part of the train journey is horizontal straight line then we can say that it has the constant or uniform velocity and zero acceleration because the velocity is not increasing at any point hence it has the zero acceleration.
