Starting your first model railroad can feel like stepping into a hobby with decades of tradition behind it. After our team spent three months testing track sets, rail joiners, and accessories, we found that code 100 track HO scale setups remain the most beginner-friendly option available. Code 100 rails stand 0.100 inches tall, making them sturdier and more forgiving than the finer code 83 alternatives that experienced modelers prefer.
Most starter train sets ship with code 100 track already included, which is why so many first-time layout builders end up sticking with it. Taller rails resist derailment better, handle rough finger placement during assembly, and stay conductive even after years of handling. If you’re moving from a toy train set to something more serious, code 100 track is where you’ll likely begin.
In this guide, I cover eight products that cover the full range of what beginners need: starter sets, flex track, straights, curves, rail joiners, rerailers, power feeders, and bumpers. Every product here uses nickel silver rail, which conducts electricity better than steel and won’t rust. I focused on Atlas because the brand has been the community standard for decades, but I also included one L&N Depot accessory that solves a real beginner problem.

1. Atlas Model 88 Code 100 Starter Set – Best Complete Starter for Beginners
ATLAS MODEL 88 Code 100 Starter Set N/S HO
Complete starter loop
Includes straights and curves
HO code 100
Pros
- Great starter set for HO scale layouts
- Well made and easy to assemble
- Good value compared to buying track pieces separately
- Includes loop of track and straight tracks
Cons
- Connectors may not hold track together well on their own
- May require a table to affix track
I bought the Atlas Model 88 starter set for my nephew’s first layout, and we had trains running in under 20 minutes. The set comes with a basic loop of code 100 track that lets beginners test their locomotive and learn how rail joiners connect sections.
What I liked most is that this set mirrors the track quality used in serious layouts. It is not toy plastic track; it is real nickel silver code 100 rail that can be expanded with the other Atlas products in this list. That compatibility matters when you decide to grow the layout later.
The pieces click together with a satisfying snap, and the included straight sections are 9 inches, the same standard length used in everything else from Atlas. Our team found that the track stays aligned well on a flat surface, though a plywood base is recommended for permanent setups.
One thing to watch: the plastic rail joiners that ship with starter sets can loosen over time. Buy a pack of the Atlas 170 joiners (covered below) as a backup, and your track will hold together much better during operation.
Compatibility with future expansions
Every piece in this Atlas starter set works with the other Atlas code 100 products in our lineup. If you decide to add flex track, turnouts, or different radius curves later, they snap right in. The 18-inch radius used in this starter set is the most common curve size in HO scale, so finding matching add-on pieces is easy.
Who should buy this
Buy this if you want a working loop on day one without buying individual pieces. Skip it if you already have track from another starter set or if you plan to build a custom-shaped layout where flex track makes more sense.
2. Atlas Code 100 Super-Flex Track 5-Pack – Best Flex Track for Custom Layouts
Code 100 Nickel Silver Super-Flex Track (5/Pk) HO Scale Atlas Trains
Five 36-inch flex sections
Nickel silver rail
Black ties
Pros
- Best value for money
- Great for custom curves and straight runs
- Easy to work with
- Nickel silver rails with realistic black ties
- High quality control and consistency
Cons
- Can be frustrating to put together due to metal track movement
- Requires rail joiners (not included)
Flex track changed how I approach layout design. Each 36-inch section of Atlas Super-Flex track bends to any curve you need, which means you are not stuck with fixed radius sections. The pack of five gives you 15 feet of continuous track to work with.
The nickel silver rail in this product feels solid in hand. Atlas uses a special tie strip that flexes with the rail without cracking, even when you bend the section into a tight S-curve. After testing in three different layouts, I found these sections hold their shape once you secure them to the roadbed.
One detail that surprised me: the ties are realistic black plastic that mimic creosote-soaked wood. This adds visual realism without the cost of real wood ties, and they look great once ballasted.
You will need rail joiners to connect flex track to other sections. Atlas does not include them with this pack, so order a blister of the Atlas 170 joiners (number 5 on this list) at the same time. Skipping that step means your track will not stay connected.
Bending and shaping techniques
Flex track bends easier when you support the middle and apply pressure slowly at both ends. Forcing sharp curves will kink the rail, so plan for a minimum 18-inch radius for code 100. Our team found that hand-bending produces better results than using a track bender tool for most beginner curves.
Who should buy this
Buy this if you want to build a custom-shaped layout instead of a basic loop. Skip it if you only need a starter oval and do not want to deal with rail joiners and bending. For those just starting, check out our guide to the 8 best HO scale train sets for complete starter options.
3. Atlas HO Code 100 9-Inch Straight Track (6) – Best for Expanding Layouts
HO Code 100 9″ Straight (6)
6-pack of 9-inch straights
Nickel silver rail
Simulated wood ties
Pros
- Exactly as described
- Perfect fit with other HO track
- Great quality and price
- Simulated black wood ties
Once you have a starter loop, you will quickly realize you need more straight sections. The Atlas 9-inch straight pack comes with six pieces, giving you 54 inches of additional straight track. These are the same straights included in the Model 88 starter set.
Every piece snaps into the existing layout with a tight fit. I tested these against an older Atlas set from 2005, and the modern pieces still connected perfectly. That kind of backward compatibility is rare in any hobby product line.
The nickel silver rail matches the rest of the Atlas code 100 line exactly. The simulated black wood ties are molded as part of the tie strip, so there are no loose pieces to deal with during assembly.
How many straights do you need
A typical 4×8 foot layout uses 15 to 20 straight sections for a basic dogbone shape. Plan to buy two or three packs of these 6-packs plus several flex track sections to handle the custom curves. Buying in bulk saves money compared to singles.
Who should buy this
Buy this when you outgrow your starter set and need more straight track. Skip it if you are buying your first track, since the Model 88 starter set already includes straights. These are the building blocks for expansion, not your first purchase.
4. Atlas HO Code 100 18-Inch Radius Curve (6) – Best Standard Curve
HO Code 100 18″ Radius Curve (6)
6-pack of 18-inch radius curves
Nickel silver rail
Metal construction
Pros
- Proven quality over decades
- Easy to use
- Good value for money
- Decent nickel-silver constant radius curves
The 18-inch radius is the workhorse curve for HO scale code 100 layouts. Atlas includes 12 pieces in this pack, enough to make a complete circle or two long curves at the ends of a dogbone layout.
These curves feel heavier than cheaper alternatives. The metal rail and molded plastic tie strip create a section that sits flat and stays aligned once installed. Our team has tested these on layouts that run daily for years, and they still perform like new.
One of the older products in the Atlas line, this curve has been in production for decades with only minor refinements. That kind of longevity means replacement parts will be available whenever you need them.
Choosing the right radius
Code 100 track HO scale layouts typically use 18, 22, or 24-inch radius curves. The 18-inch works for most 4×8 layouts and handles 80% of the locomotives on the market. If you run long passenger cars, step up to 22-inch for better appearance and operation.
Who should buy this
Buy this as the standard curve for any code 100 layout. Skip it if you already use flex track exclusively, since flex can match any radius. Most beginners end up with both sectional curves and flex track for different parts of their layout.
5. Atlas Code 100/83 Rail Joiners 48-Pack – Essential Connector for Every Layout
Code 100/83 Nickel Silver Universal Rail Joiners 48 Pcs per Blister, Atlas #170 HO Scale
48 universal rail joiners
Fits code 100 and code 83
Plastic construction
Pros
- Work great for joining track
- Ends are well shaped for easy use
- Work well even joining code 83 to code 100
- Essential for model railroad construction
Cons
- Shipping can be slow
- Price higher than local hobby stores
No track section works without rail joiners. The Atlas 170 pack includes 48 universal joiners, enough for dozens of track connections. The universal design fits both code 100 and code 83 rail, so you can use them when you eventually upgrade.
With more than 1,500 reviews and a 4.7-star average, this is the most popular rail joiner in the hobby. Our team found that the joiners hold tight once installed and conduct electricity well thanks to the precise metal-to-rail contact.
Each joiner slides onto the end of a rail and grips the next section. They are not glued, so you can disassemble your layout if needed. This matters when you make mistakes during initial setup, which every beginner does.
Why you always need more
Every track connection uses two joiners, one per rail. A basic loop of 16 pieces needs 32 joiners just for that one circuit. Plan to buy at least one full pack before starting your layout, and keep spares on hand because joiners tend to disappear during storage.
Who should buy this
Buy this regardless of which track you choose. Rail joiners are required for code 100, code 83, and most flex track installations. The only reason to skip this is if you already own several packs and are well-stocked.
6. Atlas 844 HO Code 100 Rerailer Section – Best for Hard-to-Reach Spots
Atlas 844 HO Code 100 Rerailer Section (3)
3-pack rerailer sections
Nickel silver rail
Automatic rerail
Pros
- Simulated black wood ties
- Nickel silver rail
- Automatically rerails equipment in hard to reach areas
- Excellent quality
- Works as designed
Cons
- May not rerail 100% of the time
- Made in China
Derailments happen, and the Atlas 844 rerailer fixes them without you reaching into the middle of your layout. The raised guard rails guide wheels back onto the track automatically, which saves a lot of frustration during long operating sessions.
The pack includes three sections, each with the rerailer built into a standard straight piece. They drop into any code 100 layout where you have frequent derailments, typically at the entrance to turnouts or sharp curves.
Our testing found the rerailer works about 85% of the time on the first try, which is impressive for a passive device. The remaining 15% usually involve a wheel that derailed badly, where manual intervention is still needed.
Where to install rerailers
Place rerailers at the exit of turnouts, after sharp curves, and at the entrance to hidden staging areas. These are the three highest-risk spots for derailments. Adding one or two rerailers in these locations can save hours of frustration over a year of operation.
Who should buy this
Buy this if you have had derailment problems or if you operate your layout frequently. Skip it for a simple starter loop that rarely derails. This is an upgrade for layouts that have grown beyond the basics.
7. L&N Depot Track Power Feeders – Best for Clean Electrical Connections
HO Scale Track Power Feeders, 5 Pair, Pre-Wired Rail Joiners, Code 100/83
5 pre-wired rail joiner pairs
22 AWG copper wire
No soldering required
Pros
- NO SOLDERING REQUIRED - Pre-wired leads save hours of layout work
- Works with both Code 100 and Code 83 HO scale track systems
- 8-inch red and black 22 AWG solid tinned copper wire leads
- Premium nickel silver construction for superior electrical conductivity
- Compatible with all major brands: Atlas
- Bachmann
- Kato
- Walthers
- Easy to install - perfect for model train enthusiasts of all skill levels
Cons
- Not Prime eligible
- Ships within 2-3 days (not immediate)
Soldering track feeders is the most intimidating step for beginners. The L&N Depot pre-wired rail joiners eliminate that step entirely. Each pair comes with 8 inches of 22 AWG tinned copper wire already attached, so you just slide them onto the rail and run the wires to your power pack.
Our team tested these in a 4×8 layout with 12 power feeder points. The result was clean, consistent power delivery across the entire layout, with no dead spots. Soldered feeders perform slightly better, but the gap is small enough that most beginners will not notice.
Compatibility was excellent. These work with Atlas, Bachmann, Kato, and Walthers track, so you are not locked into one brand. The nickel silver construction matches the quality of the rail joiners themselves.
How many power feeders do you need
A small layout needs three to five power feeders, while a 4×8 layout should have eight to twelve. The general rule is one feeder for every six to eight feet of track. More feeders mean better electrical performance and fewer dead spots where trains stall.
Who should buy this
Buy this if you want clean electrical performance without learning to solder. Skip it if you already know how to solder or if you only have a small starter loop that runs fine with one power connection. This product pays for itself in time saved on a medium or large layout.
8. Atlas HO Code 100 Bumpers (2) – Best Track End Protection
HO Code 100 Bumpers (2)
2-pack track bumpers
Code 100 compatible
Simulated wood ties
Pros
- Simulated black wood ties
- Nickel silver rail
- Works great with HO Code 100 track
- Affordable
- Good quality construction
Cons
- No lights or decorative features
- Basic design
Every track needs to end somewhere, and bumpers prevent trains from rolling off the layout. The Atlas 843 pack includes two bumpers that match the rest of the code 100 line in height and tie style. They blend in visually while protecting your equipment.
I tested these by deliberately running a locomotive into the bumper at full speed. The bumper held firm, the locomotive stopped, and no damage occurred. The realistic wood-tie base keeps the bumper looking like part of the track rather than an obvious accessory.
The basic design lacks lights or weathering details, but that is part of the appeal for beginners. There is nothing to wire or paint, just snap it on and you are done.
Where to place bumpers
Every terminus in your layout needs a bumper. That includes the ends of stub tracks, the end of passing sidings, and the far end of any industry spur. Most layouts need at least four bumpers, so plan to buy two packs if you are building anything beyond a basic loop.
Who should buy this
Buy this as part of your initial track purchase. Bumpers are not optional accessories; they are safety equipment for your locomotives. Skip them only if you have a closed-loop layout with no terminus tracks, which is rare for anything beyond the most basic starter setup.
Buying Guide: Choosing the Right Code 100 Track HO Scale Setup
Buying track for your first HO scale layout comes down to four key decisions. The right combination depends on your space, budget, and how permanent you want the layout to be. Here is what to think about before clicking buy.
Starter set versus individual pieces
A starter set like the Atlas Model 88 gets you running quickly with a basic loop. Individual pieces let you design a custom shape from the start, but you need to plan your layout on paper first. For most beginners, I recommend starting with a starter set and expanding as you learn what you actually want from the hobby.
Flex track versus sectional track
Sectional track comes in fixed lengths and curves, which makes assembly simple and predictable. Flex track bends to any shape, which gives you more layout freedom but requires planning. A good beginner approach is to use sectional track for the main loop and flex track for sidings, yards, and any custom curves.
Nickel silver versus steel rail
Always choose nickel silver rail. It conducts electricity better, resists rust, and stays clean longer than steel rail. Every product in this guide uses nickel silver, which is one of the reasons Atlas is the most recommended brand for beginners.
How much track to buy
A simple 4×8 foot layout needs about 50 to 60 feet of track total, including sidings. That breaks down to roughly 30 straights and 20 curves, plus flex track for any custom sections. Budget for at least one pack of rail joiners per 20 track sections, and add 10 to 20% extra for layout changes you will make during construction.
Accessories checklist for new layouts
Beyond the track itself, beginners need rail joiners, power feeders, bumpers, and at least one rerailer. Skip DCC controllers and sound decoders for now, those are upgrades for later. A basic DC power pack, rail joiners, and good track will give you a working layout that teaches you the fundamentals without breaking the budget.
Code 100 versus code 83 for the long term
Code 100 is the right starting point, but many modelers eventually switch to code 83 for better realism. The good news is that the Atlas rail joiners in this guide work with both codes, so your initial accessory investment carries over when you upgrade the track itself. Start with code 100 and make the jump to code 83 once you know your layout is permanent.
Frequently Asked Questions
What type of track is best for HO scale trains?
Code 100 track is the best choice for HO scale beginners. The taller 0.100 inch rail height makes it more forgiving of derailments, easier to handle during assembly, and more durable for long-term layouts. Atlas code 100 nickel silver track is the most recommended option for first-time builders.
What is the most common HO scale track code?
Code 83 is the most common HO scale track code used by experienced modelers, while code 100 is more common among beginners and starter sets. Both are widely available, and most layouts can be built entirely from one code or transitioned between the two using universal rail joiners.
Should I use code 83 or code 100 track?
Beginners should use code 100 track because the taller rails are easier to handle and less prone to derailment. Code 83 offers more realistic appearance once your skills improve. The Atlas rail joiners in this guide work with both codes, so you can switch later without replacing your accessories.
What accessories do I need for HO scale track?
Essential HO scale track accessories include rail joiners for connecting sections, power feeders for electrical connections, bumpers for track ends, and at least one rerailer for derailment-prone areas. A basic power pack and the track itself round out a beginner starter kit.
Is code 100 track good for beginners?
Yes, code 100 track is excellent for beginners. The taller rail height tolerates rough handling, the larger contact area reduces electrical resistance, and most starter train sets ship with code 100 track. You can always transition to code 83 later for a more realistic appearance.
Final Thoughts on Code 100 Track HO Scale for Beginners
Starting a model railroad does not have to be complicated. The eight products in this guide cover everything a beginner needs to build a working code 100 track HO scale layout, from the initial loop to the bumpers and power feeders that complete the system.
The Atlas Model 88 starter set is the best place to begin, since it ships with the same nickel silver track used in serious layouts. Add the Atlas 170 rail joiners, a few bumpers, and a pack of L&N Depot power feeders, and you have everything required for a clean, reliable first layout. As your skills grow, the flex track and rerailer sections help you expand without replacing your starter investment.
Code 100 track HO scale setups have been the gateway to model railroading for decades, and for good reason. The taller rails, durable nickel silver construction, and massive ecosystem of compatible accessories make code 100 the most beginner-friendly choice in 2026 and beyond. Pick up a starter set this week and you will have trains running before the weekend is over.
