The audio track is 5.1 DTS-HD Master Audio, but you might not guess it in a blind test. The character voices are inconsistent level-wise, and seem to have taken a back seat to the rest of the track. The score for the film is quite nice, but doesn't do much to take advantage of rear channels, and sound effects often needlessly overpower the rest of the track. By and large, the audio is not terrible especially by low-budget film standards, but one always hopes for more.
Extras for this disc are thin, but standard. First up is the "'Making Of' Featurette" (SD, 22:55) which yes, is actually called "Making Of." Aside from the typical fluff interviews with cast and crew, smaller budget productions tend to be more interesting when it comes to the nuts and bolts of pulling everything off on a tight schedule. And this featurette gives a decent glimpse into lean movie making, from the limited set to mixing in effects with live action. The other main feature is a collection of raw interview footage of the cast and crew (SD, 28:13). It's basically unwatchable, as it is nothing more than minuscule, random clips of interviews, the source footage for the editor to use later. If nothing else, it gives you a better appreciation for what an editor has to sort through to put together the featurette, for example. A photo gallery and trailer are also included.
Night Train is a decent film, and could be much worse. It's just unfortunate that it feels closer to something that could have been much better. I'm sure that low-budget independent films are under loads of time and monetary constraints as it is, but the result befits the lack of thorough development seen elsewhere. As a sloppy Hitchcock film, Night Train may well be worth a rental for fans of the genre, but falls short as something deserving of a purchase.
