If the government built a train station on the middle of the trail, then they would literally be required to build ADA-compliant ramps down to the mud.

I don't understand why people are so deeply muddled about this.

There is no train station.

It's for bridges over the railway in the middle of nowhere, far from train stations, along country footpaths.

You cannot traverse the footpaths on a wheelchair, so you cannot even get to the bridge in the first place.
