Ok so I downloaded a freeware engine and when I loaded it into a route in surveyor and went into quick drive it ran fine. Then I decided to add a consist, I picked the default us freight 1000 ft or whatever and when I went to hook up my engine went right thru the car like it didn't exist. I figured ok maybe it's the consists fault but today I was tryin out a different engine I downloaded and used default us coal consist and viola it hooked up! Question is what happened in the first scenario and is it an issue with the engine or the consist?
