Carry on bicycle service is available on only a few trains and even then there are very few spots. You can easily run out and there's nothing you can do with your bike at that point.
If you really look into it you'll discover that the notion that checked bikes are available on most trains is a lie. There are so many exceptions. Just because it's available on a train, doesn't mean it's available at your station. Only the bigger stations allow them and you have no way of getting your bike off the train otherwise. So if you want to go somewhere nice to bike around, you're mostly out of luck.
I'm not going to deal with taking the handlebars and pedals off all the time in a train station.
What am I going to do with that box? I ride my bike to the station.
The checked bike thing is horrible even if you're willing to deal with all of this insanity.
> Amtrak is not the best, but still better than air travel for cyclists. For the cost of a flight + bicycle baggage fees I can get a room on Amtrak.
Air travel is far cheaper than Amtrak in the Northeast. Checked bicycles are about $40 to fly with if you pick the right airline and $20 on Amtrak. But what's even cheaper is travel by car. Just rent a car for the day and you don't need to deal with any of this.
