Y'know, after reading the Globe's item on the MBCR's quiet car instruction video, I was hoping for a zippy, fun, media-savvy video that would illustrate quiet car rules with hammy overacting, simulated quiet-car confrontations, something. Nope. It's at the other end of that continuum, the one with employees "acting" as passengers and monotonous official soundbites. Not surprisingly, the conductors, who are used to talking in public, do the best.
Also worth noting: the bit about how the quiet "is expected to be maintained purely by mutual respect for one another." In other words, don't expect the conductor to get involved.
