Last week I did a 4×10 layout using the v11 and v16 sets. The biggest problem with the layout was moving a train from the outside track to the inside track, which is where the reverse loop was located. This week I modified the layout to shorten the trip. I created an overpass that goes from the outside track directly to the inside track.
The video shows how easy it is to use the overpass to move from the outside to inside track and then reverse the train using the revere loop.
The layout features four storage turnouts. One of those is on the outside track. As a bonus, there is a small loop for the trolley. You can download the SCARM file here.
