Layout is ready

I have completed building own N scale model railroad layout.  I had number of rails but always just assemble them to make layout each time I play my model trains with my kids.  Now, it is somehow time consuming to everytime assembling and disassembling rails.  So I have just tried to make fixed layout so that I can easily start playing with those trains.

Here is the overview.  It is double track layout with slope and a truss bridge.  I have nailed or fixed using double-sided tape those rails or piers on plastic board. 

This layout is made from 3 modules.  The dimension is about 2.3 meters by 0.9 meters.
