Coming home on SWC, connecting to Wolverine, the guaranteed connection we are booked on has a 3 hour layover. There is a train with a 1 hour 10 minute layover. If SWC is on time, what is the best way to change to the earlier train at the last minute? On the app? What if it was really tight and we weren't sure we would make it and ran and jumped on the earlier train. Would the conductor let us change tickets on the train? Or bad idea because trains do sell out sometimes?
