A train may take longer sometimes, but I find the whole thing much less stressful, you're not strapped to the seat, you have leg room, even a table, power sockets, bring your own food and drink, and the prices are competitive.
It still takes longer than I'd like to get from Switzerland to the UK, and that's mostly due to a lengthy change in Paris.
I think in France, and prob other countries too, their moving to ban domestic flights that can be done on rail instead
The train takes 3.5 hours (often closer to 4 and I've had it take more than 5 just because of freight priority). The train makes 4 trips a day (one being a longer route that is usually delayed) and the timing means that any business trip will probably require an overnight stay. The train is only $27 though because both states (especially WA) heavily subsidize the route.
In the end, it really comes down to where in the metro areas your trip begins and ends as to which works out best. For us, the train station saves about an hour of ground transport time compared to the airports and we can arrive much closer to departure, so the train works best. For plenty of others, the airport will be faster and probably easier logistically.
PreCheck and Global Entry weren't around when we went to Bermuda in August 2001. It was a trip notable not only for its proximity to 9/11 - by chance, my bag was searched either before we left L.F Wade in St. George's or on arrival back in Newark, but this happened without my knowledge and I only found out about it because customs had repacked it included a note informing me of this fact inside. - and also because a trip to camp the previous week was the start of an ear infection which burst my ear drum on the plane going down.
Fun times.
However, I quite like the idea of passport control on a train happening before you embark on the departing leg of a trip. With those formalities out of the way, just collect your bags at the destination and you're free to go.
I don't know if the FAA or TSA would consider this too burdensome to implement, but it's an idea.
I haven't taken that train in many years, but they basically stop the train at the border and immigration agents board and check everyone's passport. It's scheduled to take 2 hours. Really stupid. It's a 45 minute flight, and you go through US immigration in Canada before boarding the flight.
That was the case even with the UK in the EU (maybe it's not any less onerous than an airport now actually, idk) but otherwise intra-EU over land is not an issue, almost necessarily. (But then, you might think that about Canada/US.)

There are some disadvantages, such as not being able to pickup anymore passengers until crossing the border. Probably a non-issue with Vancouver close to the border.
Or (facepalm, more obviously) Alaska for that matter?
Popular with Canadians to send parcels to and pickup gas.

A school bus runs from there to mainland USA and I suspect there’s an informal agreement to drive without stopping through Canada so they don’t have to bother too excessively with clearances.

It's better than that. Space on board is at less of a premium so train carriages can be made with plenty of room for luggage alongside passengers. No need to check baggage.
It's going to be slower and more expensive so not so many people are going to want to do it so why build more of it.
If the major stops are closer together, 'a journey' is shorter and cheaper and beats air travel, and many more people will pay for it.
That is the problem in my opinion - I prefer sitting on a train, to sitting on a plane, but for most routes I need to travel (within the US) it takes longer to get there and is more expensive than flying - why would anyone want to pay more and waste more time? You either need to be faster or cheaper if you want my business.
