I have been working with John via PM and he got the Bergen to work. I had no idea there was Problem and Peculiarities page and that the Bergen was under such a title.
Reading the post here adds some background to John's questions that he broached to me.
The single word the jumps out at me here is there word "Scenario".
The Bergen is still a Work in Progress and so is not finalized. Only routes that are finalized can have scenarios made for them. After a route receives 40 positive votes the builder can opt to "finalize" his route. The Bergen has 104 votes but I am not finished yet! There is much, much more to build.
To hopefully hold over John and others seeking scenarios, I have packed the route with static cars and locomotives that can be viewed in over a Dozen Quick drives. They are very simple, but you can tour the route. The Dundee Park and Pascack freight QD'S are constructed so that you can drop a loco or 2 down and grab a string of cars to deliver.
Everything you need to know is in the route description. If all else fails

I will jump in and get you squared away.
John welcome to the New York Division - Bergen Line!
