ADA laws exist literally to say, businesses have to spend the money to make their facilities accessible to all people.
If you are a small coffee shop you can’t say “well I’m not spending the money to make the restroom ADA because the one ADA Customer we get doesn’t buy enough coffee to make it worth the money” that’s the attitude that forced the ADA law into being.
And the same should be true of transit. All people deserve the right to be able to travel, shop in stores, etc.
Yes, the ADA laws are to make it so the disabled and/or partially disabled have the same access as those without disabilities. However, like you pointed out, if a small business refused to comply because of the cost they would be in violation of the law - the same holds true for transit ... in this case, Amtrak.
However, if that small coffee shop complied with the ADA requirement and made one restroom ADA - they would meet the legal requirement. What happens though if two people need the ADA restroom at the same time. Should that small shop have to spend their money to build a second ADA room? ... a third?
Amtrak already meets the ADA requirement for wheelchairs. They have space for a wheelchair in each coach car and a handicapped room in the sleeper car. On the trains I have been on, they also have some seats set aside for those who use a folding chair that allows them to sit in the train seat during travel with easy access to their chair.
This situation was one where the "requested" ADA facilities exceeded the available "required" facilities - in a case like this ... who is to pay for the extras? Going back to that coffee shop - since they already comply with the ADA law by having one ADA restroom ... who should pay for an extra ADA restroom for the "one time use"?
While I can sympathize with the group that wanted to travel together - how many non-ADA groups have had to pay extra so their group could sit together? Who argues for them? Where is the news story about group of tourists that could not all sit together unless they rented the whole car at a premium price? Just out of curiosity, does anyone know what sort of fee the School Patrol pays to use the train to go to DC?
There has been mention before that the H-room in the sleeper may not be available if you do not book early ... how come there have not been any headlines about not having enough H-rooms or what it would cost to convert another of the bedrooms to ADA for a "one-time" trip because two people wanted to travel together and both wanted/needed an H-room?
BTW - I should mention, I have a handicapped placard - though not in a wheelchair, I have never seen or been provided a place to hang/store my cane at my seat while riding on the train - nor have I seen any headlines or news stories about those of us that walk with canes being provided with at seat storage for our canes so we don't have to hold them the entire time.
