Structures.This is a small mining layout based on a real 30" railroad. Follow along as we design the layout.

Benchwork drawing.
Structures.
I drew in the El Diablo trestle. This should make for a nice little isolated scene.
The compound trestle bridge over Mapimi is now called the Grande Puente (great bridge).
The large suspension bridge is now drawn in, called Puente Colgante.
The electrical blocks for the reversing loop are now marked and noted.
The rest of the structures are now installed at Ojeulo. I've added a cook house, the shacks, the office and the guard house.
The town of Mapimi is now populated with a house for Peppy, the water tower and oil tank, a retaining wall for the steep hill and a fancy adobe engine house. There is also a railroad office.
In East Mapimi we now have the important warehouse, oil distributor, the smelter ored dump with office and Pedro's palace. I've also added the towers for the suspension bridge. Very crowded indeed.
I broke out a separate drawing for the shadow box. It now contains the depot for lime loading, Rose's Cantina, water tower and oil, and homes for the Rojos and Baxters.
Excellent! Now I'll set up the main plans in a separate box on the blog and invite the folks from the LDSIG to take a look. The On30 folks too.
Just some CAD tips here. I draw my drawings in layers. A layer meaning all like components are drawn together and saves as a separate and distinct group, and usually all one similar color. These layers can be turned off and on so that you can either focus on them or move them to work on other areas. Not sure if I really explained that well. So here I'm starting a structures layer and making it brown. I do this with every layout. I'll leave it on as I work with them and turn the Grade layer off.
The mine complex needs several buildings. I'll start with the main power and machinery building. Power is generated from a oil fired boiler. We'll put double doors on it and make it a machine shop. Its the largest mine building at one foot long and six inches wide. This is so that the interior can be detailed if we want it to be.
The powerhouse can move around so I just kind of sat it in the middle. Then I drew the tipple, which is nothing but a two car length trestle over a ramp that dumps the ore into the awaiting hopper. We'll deliver the ore by Bachman's V shaped skip dump ore car. The tied track drawings are starting to get in the way, so we'll convert them to hidden trackage as both are socked away under the scenery. The top mine loop is under the rock of the mine face. The ore car track goes right to the edge of the layout and we'll put about four inches of mine tunnel and a portal there so a person can feel like they are in the mine looking out onto the mine complex. Neat, huh?
The first thing I did was add the timber tunnel portals. These things are huge in On30, so be sure to make room for them. Timber portals are hard to come by in On30, but you can get them from Dr. Ben's website. These will work nicely and we'll need a ton of them. I also drew in the mine cribbing section and the trestle work to get the mine track over to the tipple. Looking good!
