"Customer experience" is different in the long-distance trains than on the corridor trains. When I ride the NEC, my main problem with the "customer experience" is the cattle lines and gate dragons at Washington, Philadelphia, and Boston. (New York Penn gets a pass because of the limited platform area and those in the know can use the West End Concourse or lower-level stairs to avoid the cattle lines.) Some of the resulting crowding and shoving could be eliminated by having assigned seating in coach. Beyond that, for a 1-4 hour ride you really don't need much customer service. Frequent trains that are more or less on time are what really counts.I mostly see the management issues in customer experience on board. Every train feels unique based on their crew districts and what the LSA/SCA/conductor is used to doing. At best it feels charming, at worst like Amtrak management couldn't be bothered to check. Boarding feels arbitrarily airport-like, even when there is enough platform space. Lots of low hanging fruit that isn't stopped by funding.
