Finally got to start my Garden Railroad while the weather was nice to be outside. Much work has been done.
I am calling this a Hybrid Garden Railroad as it will be a combination of a above ground filled and also a platform something like Ken Brunt has made. The above ground portion will be on 2x4 joists with a layer of corrugated sheet metal, on top of that will be a layer of screen and then a layer of fabric cloth to hold the soil in place. This area will be about 4-6 inches deep in soil so live plants can be used. The corrugated area will be angled slightly to ensure water will run off and a possible channel add to collect the water and exit the railroad. The area is not level as you can see from the first picture
The short rails for the curve are cut to 22 1/8" that makes approx 10 foot diameter curve.
The long rails are 48 inches in length.
The sub roadbed has not been defined yet.
The frame work is 4x4 posts and 2x4 rails all pressure treat for ground contact.
All Rails are square cuts only,
The posts are cut at angles if needed like on a curve. See pictures for more detail.
The upper end is only 10 inches high and will be the area with fill dirt.
View is what the finished wall looks like before painting. Ran out of 2x4s on the second panel.
Back side of Panel showing how the rails are attached. I am using a Kreg Pocket Jig.
Corner Post has two 1 1/2 inches Dado’s 3/8" deep and 3/4" lip. This hides any mis-cuts on the rail ends.
Post cut for the start of the curve, notice both sides are cut at 11.25 degrees.
Post cut between two curves sections, both sides are cut at 11.25 degrees.
Post cut to end the curved section and start of a long straight rail section. The final angle cut had to be determined by using a string from the start to finish of the straight section and a compass used to measure the cut angle, it was about 6 degrees for the right side cut. The left side is just a straight dado cut.
Post at end of the straight section making a slight left hand jog to parallel the stairs. Angle cut is about 5 degress
