Our model train is a Marklin German Federal Railroad (DB) class V 60 diesel locomotive (see link) http://www.marklin.com/start/pops/81567.html
This project was commenced in 2009. Here are some pics of the original planning phase for the layout.
It was quite tedious to figure out how the tracks would best fit on the table and still have an interesting shape for the route. More photos coming soon!
