Boswald Connection, shunting layout

[hillyard999]

my layout is a small shunting yard a little off the main line.
Once having only a small woodworking shop in the basement of a house, it grew.
Now holding a larger woodworking shop, a brewery, a small good shed and a team track.
Easy to see that this yard is too small for the amount of traffic.

Hoping the pictures want to attach, and happy to no longer be lurking only

Hello Kitty,
Looks like your layout will be  a lot of fun!

I am curious about your loaded gondola.  
What did you use, it looks like maybe a roller from a printer?
I am always looking for bits and pieces I can use for loads.
