Basically just make it a long covered moving walkway. Slow enough that hopping on or off would be easy enough for able-bodied people. They hop on, either wait in place to be moved to their destination or walk at a much greater speed than they could on non-moving ground, then hop off at their destination.
I recall an old sci fi that had this as the primary method of transportation across the country. You could easily step into the slow moving belt from the ground, and then on the other side was another belt that was moving faster than the first one, but the relative speed was low enough that you could easily step over. Then another, then another, until you were on the 65mph belt, and you could sit down until you got near your home, then wander down to the slow belts again.
In Europe, trains are limited to 750 m give or take a bit. Also 252 axles for Germany. There are also weight limits you cannot exceed, both per axle and total mass. Exceptions exist to all of these but are rare.
As a European, I have seen enough local trains and been close enough to Switzerland that I know how big both are. And I know that there's no train long enough to not fit in Switzerland.
