I thought I'd put together a bunch of CSX engines to see how the app handles a train. I figure I'd better test it first!
So of course one of the engines, a dash 8?, doesn't get the very last stop or shut down commands. It was parked by mistake on a switch so maybe that's all the issue is?
The good news is I put all these engines on the rails and only the lead engine was added to the app. All the rest came right up under "add new engine" and loaded without issue.
