I looked at taking the train from my town to Glacier National Park along with my bike. The route goes from Portland and Seattle to Chicago, and has a stop at south glacier.

Step 1, get to the local train station in my town. There are 6 trains daily between me and Portland. Also, amtrak on the cross country trains requires the bikes to be in a box, in storage cars.

So I gotta get a large bike box, and get myself, my bike, the box, and some tools to break it down to our local amtrak station. Then partially dissasemble the bike, and box it. (of course, our train station has room in it for 5-10 people, and most sit outside, uncovered, which is fun in spring.)

Then, get to the main Portland Train station, with my bike box, and backpack with my stuff and tools. Wait up to 9 hours for the hawaitha train. (its often many hours late, and only leaves once per day).

Load Bike in cargo car, and then board train late at night.

Wake up around 5am, (or later, if train is behind schedule) and disembark at Glacier, re-assemble my bike. Figure out how to get it, and the box (i'll need it for the return trip) to a hotel or AirBnB.

For the return trip, its about the same, 1 daily westbound train, that is usually hours late, then hope you get to portland before the last train for the day leaves for my town, or else find a place to stay with a bike, backpack, and bike box in the sketchy area around the trainstation...

Or, hop in a car with a bike rack, and drive 10 hours. Which is easier, and MUCH cheaper if I split the cost of gas with someone else. So 2 extra travel days back for vacation, and much less stress.

Most of this is just that the US rail system is amazingly shitty by global standards.
