This is for a custom built N scale single or double track vertical lift bridge. The double track version is what appears in the photo. The price includes shipping in the US. The bridge measures about 14” long and roughly 8 ½ “ high each tower. It is made out of styrene plastic. I will install whatever N scale brand of track that you prefer. A motorized version of this bridge would be $150 extra which would also require mounting it on a (base) module. This module would be custom built to fit perfectly in your layout. I also custom build other types and scales of bridges for railroads or roadway. Just click the Model Railroad Layout Builder link to check out pictures on my web site of bridges and layouts. On eBay I am LAYOUTSNBRIDGES. Thanks for looking.
