Dec 22, 2012 at 15:21 comment added Popopo @LubošMotl if point $i$ is far from the window enough, then $v_i=0$, $\rho_i$ and $p_i$ seems same like the train is static.
Dec 22, 2012 at 14:18 comment added Luboš Motl Why do you think that $\rho$ and $p$ are the same? Surely if the window may be a discontinuty for $v$, it may do the same for $\rho,p$, right? Otherwise an open window is needed but the equation is designed exactly for such situations and yes, it holds in any inertial frame, like any classical physics principle.
