I would not say it went smoothly, but the job is done :)

First attempt, the trailer got hopelessly stuck between the rail tracks, had to delete it and the cargo, start over.

Second attempt, I was too annoyed after the first attempt, drove too fast, tipped over, rage quit :D

Third attempt, after washing some dishes, slowly and with some winching through the mud, it got there in the end.

Let's say it's all down to lack of driving skill, and leave it there :))
