Accessory parts
Looking for accessory parts that help restore small locomotive details, improve function and keep your model railway fleet complete and convincing?
Then you are in exactly the right place: with the right locomotive accessory parts, detail parts, lighting parts, body components, gear parts, handrails, windows, lanterns and other model-specific spare parts, you can repair visible damage, restore lost functionality and keep your locomotives ready for dependable and attractive operation.
What are accessory parts in model railways?
Accessory parts are the smaller technical and visual spare parts that help complete, repair or upgrade a locomotive beyond the main drivetrain and standard wear items. They often include body details, fittings, lighting parts, PCB-related components and visible mechanical elements.
In this category, the visible range is especially broad. It includes items such as crank pin sets, counter cranks, rerailers, brake hoses, axle gears, handrails, front windows, LED lighting boards, main PCBs, lanterns, snow ploughs, gear sets and other model-specific small parts.
For you as a buyer, this category is especially important if the locomotive is basically intact but needs exact replacement parts to look right again or function correctly in everyday operation.
Why are locomotive accessory parts so important?
Many locomotive repairs are not about motors, decoders or full chassis units. In practice, a model often needs smaller but very specific parts such as a missing handrail, damaged lantern, worn axle gear or broken window section. That is exactly where accessory parts become essential.
These parts are especially useful because they allow very targeted repair work. Instead of replacing a full body or giving up on a model, you can often restore the missing detail or function with one correctly matched part.
This makes the category highly practical for restorations, used-model repairs, long-term fleet upkeep and anyone who wants locomotives to look complete and run convincingly.
Which products belong to the accessory parts category?
The category contains a very wide mix of mechanical, electrical and visual spare parts. Visible items include crank pin sets for BR 80, counter cranks, cab and engine room lighting, rerailers, brake hoses, axle gears for older models, handrails, direction indicators, LED front-light and interior-light boards, main PCBs, housing parts, chimneys, lanterns with LED, gear sets and snow ploughs.
Visible examples include products such as Piko 36093 crank pin set BR 80, Piko 56080 counter cranks with crank pins, Piko 36017 cab and engine room interior lighting, Gützold axle gears for models up to 1992, Hummel-Modell handrails and tail lights, Hummel-Modell LED front-light / LED interior-light connection board, Piko main PCBs, LGB normal chimney 18 volt, Modellbau Veit painted base plate, Piko lanterns with lens or LED and Piko H0 snow ploughs.
This makes the category especially useful because it supports many different repair depths at once, from simple cosmetic restoration to targeted electrical or mechanical replacement work.

Which brands are especially important in accessory parts?
The category is highly brand-specific because accessory parts are often designed for exact body shells, locomotive classes or internal layouts. The strongest visible brand is Piko, followed by Hummel-Modell, Weinert, Roco, Bemo and LGB. Additional visible brands include Artitec, ESU, Gützold, Märklin, Merkur, Modellbau Veit, pmt and Tillig.
Piko is especially important because it covers a very broad range of parts from crank pins and brake hoses to lighting sets, windows, handrails, main PCBs and body components in H0, G and TT. Hummel-Modell is highly relevant for fine H0 detail parts such as handrails, brake wheels, seats, signal boxes and decals. Weinert and Modellbau Veit are especially useful for more specialised and detail-oriented repairs.
Roco contributes selected replacement items such as cabins and cleaning-related accessories, while Bemo supports specialist narrow gauge needs and LGB adds larger-scale parts such as a normal chimney. This broad brand spread makes the category especially useful for exact, model-specific repairs.

Which gauges are especially relevant for accessory parts?
The category is especially strong in H0, followed by G, TT, H0e, H0m and smaller support in N, 0 and 1. This makes H0 clearly the most important scale for this category.
H0 benefits the most because it combines the broadest locomotive fleet with the widest range of visible accessory parts, from handrails and lanterns to PCBs and body elements. G is also highly relevant, especially for larger visible parts such as housings, chimneys, steering parts and lighting items. TT and narrow gauge support are smaller, but still very useful for exact specialist repairs.
Gauge overview for accessory parts
When should you replace accessory parts?
You should consider replacing accessory parts when a locomotive is still mechanically worth keeping but shows missing, broken or damaged visible elements or exact secondary functions. Typical examples include lost handrails, worn axle gears, broken lanterns, damaged windows or missing brake hoses.
This category is also very useful when restoring used locomotives, because such models often need smaller exact parts rather than a full body or chassis replacement. Visible products such as main PCBs, windows, lanterns, handrails and gear sets show that the category supports both appearance and function.
What is the advantage of buying model-specific accessory parts?
Model-specific accessory parts are especially useful because they match the original body shell, mechanical fitting or internal layout much more precisely than universal parts. That matters a great deal when you are replacing items such as windows, handrails, crank pins, lanterns or PCB assemblies.
The more precisely a spare part matches the locomotive family, the more convincing the final result will usually be, both visually and functionally. This is one of the main strengths of the category.
Which accessory parts are especially good for beginners?
For beginners, the most approachable products are usually simple visible replacements such as handrails, brake hoses, lanterns, rerailers and clearly labelled lighting sets. These are easier to identify and often give very noticeable results with limited repair effort.
If you want fast visible value, replacing one missing handrail, one damaged lantern set or a small mechanical fitting can already make a locomotive look much more complete and convincing again. More advanced items such as main PCBs or gear sets are also very useful, but they are usually better suited to more focused repair work.
Beginner-friendly choices in accessory parts
Which locomotives benefit most from fresh accessory parts?
Locomotives that benefit most from fresh accessory parts are used models, frequently handled locomotives, older fleet engines and projects where the main body and drivetrain are still good but smaller exact details are missing or damaged. This is especially common in H0 and G scale, where visible parts play a very large role in the overall impression.
The category is also highly useful for restoration projects and layout locomotives that need to look complete again for visible front-end or side-detail scenes. Items such as lanterns, handrails, windows and lighting boards can make a surprisingly large difference in how finished a model feels.
Typical uses for accessory parts
What should you look for when buying accessory parts?
When buying locomotive accessory parts, you should pay special attention to brand, gauge, part type, body or internal application, mechanical or electrical purpose and the exact locomotive family involved. These factors matter because accessory parts are often highly model-specific.
It is especially important to ask whether you need a visible detail part, a lighting element, a gear-related small part, a PCB or a specific shell component. The more precise the match, the more convincing the repair result is likely to be.
A careful choice is usually much more valuable than buying a roughly similar part. The best accessory part is the one that restores exactly the missing function or visible detail your locomotive needs.
