Is this really an ADA requirement? Moynihan, which is far newer, doesn't have it, and AFAIK neither do any of the other stations anywhere in the country.
The handful of times I've been to CUS, it's been very confusing to me. The wayfinding is much too small and there are too few signs. Like Grand Central, the main hall is gorgeous, but the actual train areas are dilapidated, cramped, devoid of light, stinky, and very loud, especially in CHI with all-diesel services. I don't understand what's so difficult about having a complete ceiling with no holes, a welcoming waiting area that doesn't look like a Greyhound terminal from the 80s, and employees that don't bark at you right and left.
It seems everything in CUS is a mess, from the boarding process to the waiting area to the incompetent maintenance facilities. I just don't get it; it's one of the most important rail facilities in the country.
