Mostly. If your locality is served by Amtrak - and only a few dozen cities are out of the 3 million square miles of ConUS - then it can be somewhat convenient and cost effective if you plan your travel more than 2-3 months in advance. It’s about 2/3 the speed of car travel, but more comfortable, generally. If you buy tickets less than 3 weeks ahead the prices are about 4x what they are for booking at 3-6 months out. Also, unless you live in one of the 2-3 hub areas, trains run only once or twice a day. For comparison, Last time I checked it’s like £70 to go from London to Aberdeen and takes 7 hours and trains leave every hour or two. From Roanoke to New York - 80 miles closer than the UK route I know of - it’s $200, 9 hours, and only two trains run per day - the first departs at 6:20am, the second at 4:15p (and gets in around 2am). It’s only a 7.5 hour drive and $40-50 in gas to go from Roanoke to NYC, and it’s pretty easy to park outside the city and take a commuter train in.

Oh, and there’s no workable hub and spoke system due to the few trains and long travel times. My daughter is just 300 miles away at school and the city has a train stop. It’s a 5 hour drive one way. It takes two days and 3 train changes to get from her city to the closest station to me, about a 45 minute drive away. It’s ridiculous.
