On the assumption that passengers don't step directly onto a lift on
emerging from a train in option 2 , what exactly is the difference?

Train to street means level access, which you need if you are in a
self-propelled wheelchair. Platform to street means that there is a
single step from the platform to the train, which is not a show-stopper
if you have someone pushing you.
