This is the side view of my East-West middle module. It is a STANDARD- Z Bend 3' x 3' module.. with trains above and below the mainline tracks. I can run one train above ( crazy 8 )and two ( sort of roundy- roundy ) below the Z Bend mainlines- Idependant of other modules. When I complete the two end units I may be able to run more trains. :-) This has been hooked up to the DC group modules in Timonium and has proven to work well with others. The two sets of mainlines are: on left- between the two buildings that look sort of like grain elevators--- and on Right--between tall black "cliff" and windmill. These two sets of 2 tracks mate with other modules. The curved tressel is part of the figure 8 for upper train. The section on right with lighthouse is a bolt on extension that is cantilevered and braced to add additional area for harbor scene.<br />Not shown in this picture is the 20" bolt on drop down on the left that allows two more trains to run below and under the main line. The mountains that curve down the middle keeps each scene from being viewed across the module. Total height from lower facia board on left to mountain top- is about 42".
