Upper Level Track Clearance And Gradient

Shane models HO and asks readers:

“I want to run a double track to a proposed new upper level on my 4×9 setup and want to know how high to make it above the lower level. I don’t want the gradient too steep but still want enough clearance for access and for trains to run under the top level. Sorry if that sounds confusing.”

    Hi Shane, I run a double level in OO scale.The distance between levels is 15 inches, this sounds a lot but believe me when trying to access something at the back of the layout it’s pretty tight.Any way I’ll tell you how I did it, firstly my layout is in a U shape, 3.2 x 3.2 x 3.2 metres. To gain another level I built a double track helix at both ends one for going up one for going down, then after putting down the base boards it was quite dark so I had to add led strip lights. You could build a helix at both ends or even just one end. The gradient I used was 2% mainly because I like long rakes of wagons and a decent loco can manage this quite easily at that grade.The down side is I used 3rd & 4th radius track which in turn made the helix pretty much a 4foot square and the amount of track required huge, but you could use flex track. The helixes work very well, but as I was saying take up space, one other thing if the distance between levels was any lower it makes viewing hard and you lose interest in the lower level and concentrate on the upper level so you may as well have left it at one level.hope this helps regards Graeme

    Shane == If you want a second level on your 4 foot by 8 foot table, you would have to start raising the track at the 8 ft edge of the table. You will need that much to get a nice rise so trains may pass under the raised track. You need at least three to four inches to do this.
    That also depends on the size ( height) of your rolling stock. Double stack cars may require more space to pass under. I hope this helps you. The best thing you could do is to expand your layout space by another table. Good luck and stay in touch.

    Hi Shane; I am in the process of creating a 15.5 ft x 17 ft room in the back of my 2 car garage for a multi-level HO scale layout. I designed plans to have an upper shelf style continuous loop double main passenger level above a larger freight/ switching level that is an extended dog bone style. In designing the passenger level, I want the run to go from a 60 inches at the main station along the back wall to 72 inches along the front wall with a mountain town and a bridge over the doorway. In order to fit the 12 inch rise into the 15.5 ft width and keep the ascending grade at 3% or less, I have to include a 50 inch radius Tehachapi loop on one side. On the other side a 120 inch L x 54 inch W rounded peninsula will give me a less than 2% grade for both mainlines. So to answer your question: you would need a larger layout or a double helix, which would take up about 4 sq ft., in order to get the desired separation between levels. Best of luck, Tim

    I HAVE A 12FT. LONG BY 4FT. AND I USED A 2 TO 3 DEG. W/ HELIX. IT SAVE ME A LOT ROOM. I USED FLEX TRACK AND SOLDER THE ENDS. ALSO I PUT STRIP LED’S UNDER NEIGH. IT LOOKS GREAT.

Use Tiny Railroad Micro Controllers

A micro controller is basically a small programmable computer device to help hobbyists “make things operate.” It is clever way to realistically replicate the movements, actions and functions you are likely to see on a full size railroad.



Micro control technology can be used for:

Rolling stock and scenic lighting effects, street lamp lighting, lighting up of structures, emergency vehicle flashing lights, replicating a campfire or arc welding, tall structure tower lighting, block occupancy detection, turnout operation, motors/servos, solenoid, infrared, right-of-way signal lighting, current sense, crossing gate & signal operation, semaphores, flashers, turntable control, gate arms, draw/lift bridge control, fast time clock, DCC testing, scenery sound control, wireless controls, and lighting fixture day to night control.

The good thing is; a micro controller can be programmed to perform one, or just a few, simple tasks over and over again.

Why DCC is so popular

A simple DC (Direct Current) transformer will give you a nice chugging locomotive going one way on your model train track, however, with a DCC unit you can have the flexibility of having an entire train-switching yard happening right in front of your eyes! That is the adaptability that is available with this coming-of-age technology in the hobby!



By using the Digital Command Control, you are opening up a whole new range of possibilities. A continuous electrical current is sent to all of the many things you have installed on your train layout, however, now you have a digital receiver installed in each various items. You can therefore control each and every one of them with the selectable controller and enhance the operation and, more importantly, the look and feel of your system.

The technical side of the DCC is, actually, not as complicated as you might think. In reality, a DCC system is usually easier to wire than a straight DC system.

Deciding the Era and Location

The choice of scenery you decide on all depends on what era and location you are depicting with your layout. You will need to do some good research on the railroad and its surroundings to make sure you get the scenery perfect (if that’s what you want).



If you are depicting a historical train setting or a certain era, you will want to use old photographs to determine how the scenery should be built and laid out. Remember to think through all aspects of the scenery. This is one of the best areas to really showcase your talents, so take your time.

It’s YOUR Railroad!

Your rolling stock and locomotives might actually be the center of attention on your layout, but the scenic features that surround and envelop your layout is what's likely to make your train setup stand proud of the rest. Your selection of scenery and structures will add an element of customization that will make your railroad truly unique.



Scenery, structures, and fine detailing is a fundamental aspect of any good model railroad, particularly if it is intended to replicate a true-to-life railroading scene. How realistic or authentic you make your railroad is entirely up to you... and you alone.

Some enthusiasts like to replicate every tiny detail so as to accurately depict, in every aspect, a miniaturized version of a real life scene.

Others in this hobby adopt a more "free-style" approach and choose to mix and match accessories and features they personally prefer. Even though the purist will possibly be unimpressed with unrealistic or out of context elements, it is YOUR railroad layout so you can make it anything you personally want!
