King Stone is just about done - a few more "people" working will make it more complete. Also, attached from left to right is an overview of the railroad  - East Yard to East Tunnels to Westbound past King Stone and Ivanhoe Road Station. To the right of the station is the future bridge to the West portion of the layout scheduled for construction in January. In the foreground you can see the last two sidings to be put in that cross over one another - left going to right coal company trestle and right going to left and down to a lower level box company. 

I wish to build a model train layout depicting the lifecycle of cement production I want to start the lifecycle by building a quarry with a stone crusher and washer facility ( the glacier gravel co) leading to a cement production plant (valley stone cement co) not a ready mix plant connecting the two using a conveyer system and then finally at a later stage would like to add a ready mix plant( medusa cement co ) connecting all three facilities closer to a city or town Should I use a point to point layout system or could I use another layout format

...So I've been experimenting using sifted dirt over the painted Sculptamold, using diluted white glue, then later spraying with diluted matte medium to seal it.  The problem is that the dirt is significantly darker after it's glued down.  I thought it might be the matte medium, so I left that off.  Then I thought that maybe it was the dilution of the glue, so I reduced the water until, finally, I was using just straight glue.  That seemed to help somewhat, but the glued-down dirt still has a mottled, darker-than-natural color.  What am I doing wrong?

I want to use SMD LEDs, as shown below, To light a structure with a 12v DC power supply. I have NO information on how to wire these LEDs . I have used 3mm LEDs for loco lights so I do have some experience. I need information on polarity, why 3 contacts on each side, do they all need to be wired... I guess I need to know a lot.
