I think Bob overestimates his talents. Despite having a film degree of some kind, he's only ever worked on the equivalent of some toddlers making a play in their garage. Also he's pretty much a Literally Who when it comes to *making* that kind of thing.
Trains aren't practical everywhere. Where I live a train (that isn't at a museum) hasn't run since 2011 because nobody kept the tracks maintained (to be fair a large swath of track is through the middle of fucking nowhere and thus maintenance is not only expensive but a bitch). And to top it all off, it's a SINGLE track. For it to even be remotely feasible the track should be twinned, and that would be even MORE expensive. Every once in a while someone with a pie in the sky idea suggests fixing the train tracks so that trains may return, but I don't see that happening anytime soon due to insanely prohibitive costs and disinterest on the part of the company that owns the rail line.
Buses aren't that much better because Greyhound went under in Canada and there's very little else to take its place, cutting off vast swaths of communities from each other if one doesn't have a car.
But I don't expect Bob to even begin to comprehend this.
