Access to Machens via the trail may still be difficult or impossible as a result of 2019 flooding damage, I believe. That said, the easternmost Amtrak stations in Missouri are in the city of St. Louis and in the suburban city of Kirkwood. The trail doesn’t intersect with either station, but you can bike to either from the trail; depending on where you cross the Missouri river, this could be a ride of 17-25 miles. Most of these routes will be on streets rather than protected trails or paths. Taxis or rideshares can also transport you from the trail to either Amtrak station. I suggest Google Maps’ bicycling and public transit views to help you plan.
