Track grade is the slope of a railroad track. The track grade is expressed as the percentage of its rise for the length of its run. For example, if you have inches of model railroad track and the train climbs one inch, then the grade is 1 percent. When 25 inches of track rises 1 inch, the grade is 4 percent. Maximum grade is the steepest slope your trains can climb.
Even the largest HO scale trains will negotiate Elevated model railroad inch radius curve. These grades aren't very steep for model trains, but railriad are steep grades for real-life trains. Maximum grade is the steepest slope your trains can climb. Gauge Z Class G 8. However, curved grades have additional considerations. Many people never get beyond the design stage, afraid of not getting it right. December Catalog is Available! Graph paper can be helpful in maintaining scale.

Smile Paul Reply. Also, the yard areas are a bit small for a layout of this size. Central Valley also offers some bridge parts, including girders and lattice-work structural members. Unless you have a gymnasium available, building a true point-to-point layout in Elevated model railroad is normally out of Elevated model railroad. The four lobes created by the loops are used for four different purposes. But carving stacked foam is a common technique for building terrain and scenery apart from the track. Learning by doing might cost you. If you want to run long trains, Twin dikes marina need close-to-level track. Unfortunately, this required a 6" change in elevation, which I very quickly figured out was not going to work on a layout that size. My Layout Pics Reply. I couldn't find a source for it here. I have come to the conclusion that they are right. Also, note how using O54 switches on the Atlas plan allows for Elevated model railroad closer spacing of sidings than with O42 switches on the MTH plan. The upper right lobe is for a passenger terminal, the upper left is a small freight yard and engine servicing area, and the lower left is a mine or industrial area.
Planning a model railroad can be a hobby unto itself.
- Here's a link to the Walthers page for one of them.
- My son and I are realitively new at model railroads and are working on our first layout.
- If you have graduated from ovals and basic turnouts on your model railway, the next step is to create some elevated tracks and terrain.
- Here we will touch on the basics of O Gauge 3-rail track, the different types of 3-rail track, give some basics on layout design, and provide several track plan ideas as well as books with more ideas for turning a starter set into a miniature railroad empire.

I already have a subway and think off and on that something elevated might be neat as well. This plan provides the action of a 4-track main in a reasonable 16 by 16 foot area. One hundred inches of track per 1 percent grade per 1 inch of height is generally needed. Because this will be on a show layout i needed it sturdy so i am scrstch building it. GarGraves was the first mass produced, realistic-looking 3 rail track when it was introduced in
Elevated model railroad. Taking Model Trains to a New Elevation
Track grade is the slope of a railroad track. The track grade is expressed as the percentage of its rise for the length of its run. For example, if you have inches of model railroad track and the train climbs one inch, then the grade is 1 percent.
When 25 inches of track rises 1 inch, the grade is 4 percent. Maximum grade is the steepest slope your trains can climb. Well-planned grades can make a layout interesting. Badly planned ones can be a disaster. The simple answer you will hear from many model railroad fans is to never use grades steeper than 2 percent. However, that isn't the final answer.
The largest manufacturer of model railroad landscape materials, Woodland Scenics, offers flexible incline foam for grading model railroad train layouts in grades of 2 percent, 3 percent, and 4 percent, and they continue to sell them. These grades aren't very steep for model trains, but they are steep grades for real-life trains. In real-life railroading, there are three classes of grades: 0.
Because of this limitation in real-life trains, some builders of prototypical model railroads will ridicule any grade steeper than 2 percent, calling them " toy train " layouts.
Maximum grade is frequently dictated by available layout space. The implied requirement is that if you are building a small layout it should be flat. But why not a mountain grade railroad over a flat oval or figure eight? Maximum grade is a function of three factors: the power of your locomotives, the weight of your locomotives, and the number and weight of the cars in your trains. That the locomotive's power is a factor is common sense; a weak locomotive won't pull many cars up a grade.
But how the weight of the locomotive affects maximum grade isn't quite so obvious. The greater the weight, the greater the traction. This means wheels on lighter locomotives may slip where heavier locomotives can climb a grade. Larger scale locomotives may handle steep grades better than smaller scales.
Good N scale locomotives can pull around 15 cars up a 4 percent grade. But to some modelers, 15 cars is too short a train. With model train track curves the concern is the width of the space available to us.
While curves can be used to break up the monotony of long straight sections of track, turning a train around with a degree curve , a necessity for continuous running layouts, taxes the limits of a narrow layout.
But interesting layouts frequently pass one track over another on bridges or trestles. The table lists clearances in various scales for bridges and tunnels. Their vertical clearance standards are based on their "H" dimension. Manufacturers of trestle piers and tunnel portals generally exceed this dimension sufficiently to take into account the height of the rails for most model railroad tracks.
However, there are numerous cases where tunnel portal products don't have sufficient clearance for models of modern locomotives and cars. Pantographs on electric locomotives increase clearance requirements too.
In order to raise a track to cross over itself, as in a simple figure eight, you need a grade that will raise the track to the clearance height. The table of clearances includes the lengths of the runs required to raise the track to the specified height for 2 percent, 3 percent, and 4 percent grades in various scales.
Remember that the track must also descend back to its starting level, so this length of the grade is required on each end of the bridge. The diagram shows N scale crossovers layouts for 2 percent and 4 percent grades. Ascending tracks are in green and descending tracks are in red. The 2 percent grade layout requires over 6 yards of length for the layout. To do this you raise the base elevation by one-half the tunnel clearance height.
Then you use grades to lower your track for the under and raise it for the over. This technique requires four half-length track grades instead of two full-length track grades.
It can also make your layout more interesting to look at. The diagram shows N scale figure eights with the grades split. The 4 percent grade layout now has a length of 3 yards. The blue outer curves are the midpoints of the grades. We could further shorten the layout by making the curves part of the grade. However, curved grades have additional considerations. When you curve a grade, you increase the effective slope of the grade.
The tighter the curve, the steeper your effective grade. An example is an inch radius curve with a 4 percent grade in N scale.
An Athearn consolidation class locomotive would pull nine of its Overton passenger cars over this curved grade with no difficulty. If you made an 8. When pulling longer trains, particularly in N scale , it is common to use the prototypical practice of pulling the train with multiple locomotives.
This will also increase the size of a train that can be pulled up a grade, or the maximum grade for fewer cars. In the Steam Era, it was not unusual for railroads to have "helper" locomotives standing by to be added to trains at steeper grades.
While modern prototypical diesel trains usually put all the locomotives at the front of the train, some modelers put locomotives in the middle of a train.
Another technique is to use a ghost car or "cheater car. Ghost cars are usually put in the middle of a long train or spaced evenly throughout a long train if more than one is being used. Randgust makes a ghost car kit and Reality Reduced has a video on how to put it together.
What's My Maximum Grade? Maximum Track Grade and Train Issues Maximum grade is a function of three factors: the power of your locomotives, the weight of your locomotives, and the number and weight of the cars in your trains.
Model Railroad Layout Overpass Clearances. Continue to 5 of 9 below. Grading Runs for a Crossover. Split Your Track Grades. Curved Track Grades When you curve a grade, you increase the effective slope of the grade. Multiple Unit Locomotives When pulling longer trains, particularly in N scale , it is common to use the prototypical practice of pulling the train with multiple locomotives. Continue to 9 of 9 below. Tips Always build your layout on layers of foam with the most track at the midpoint of crossover elevation.
Then you can always split your grades going down for the under the track and up for the over the track. Test your trains on the layout before you glue down your grade foam and track. Make sure your locomotives can navigate all your turns and grades, pulling the number of cars you desire. If your favorite trains can't run on the layout, rethink your design.
There's always a solution, but sometimes it takes a while to find it. Read More.
