How to fix tracks with a missing peg (male) connector:
Peg bones repair kit for wooden railway tracks that have lost their little peg connector. Push a peg bone into the empty hole, add a drop of glue, and the track connects again.
What you get
- 5 peg bone connectors (half a dog bone, shaped to sit inside the track's hole)
Works with
- Thomas & Friends wooden railway, BRIO, IKEA, Melissa & Doug, Bigjigs, and most magnetic wooden train tracks
Quick install
1. Test fit: if the peg bone slides in snugly, add a drop of super glue or white glue to the ribbed section and press into the hole. Let dry.
2. If loose: place a small strip of paper over the hole first, then push in the peg bone.
3. If the hole is too small: drill it out slightly or shave the peg bone's ribs.
Details
- Designed and 3D printed in the USA
- CPSIA-tested, kid-safe, non-toxic plastic, ages 3+ (small parts)
Great for
- Rescuing beloved old tracks instead of replacing them
- Grandparents' train collections and hand-me-down sets
Due to hole depth varying between BRIO, Thomas, Ikea and Melissa & Doug, peg bones are sized for a one-size-fits-all snug fit but may need shaving or shimming as above.
Why this matters
A cracked or missing peg is usually the only thing wrong with a piece of wooden train track. Tossing a whole piece of track because one connector snapped is solving the wrong problem.
The wooden train track replacement pegs sold by TrainLab are sized for the standard wooden railway gauge shared by BRIO, Thomas Wooden Railway, Melissa & Doug, IKEA LILLABO, and Bigjigs. One small pack usually fixes several failure points across a mixed-brand collection, because those brands all use the same peg-and-socket system even though they package it under different names.
This guide ranks five TrainLab connector packs for 2026 by which exact track problem each one solves, not by pack size alone.
What makes the best wooden train track replacement pegs
- Fits the gauge you already own — BRIO, Thomas Wooden Railway, Melissa & Doug, IKEA LILLABO, and Bigjigs all share one wooden peg-and-socket standard
- Matches the actual failure — a broken peg, a missing spare connector.

1. TrainLab Pegbones: best wooden train track replacement pegs for fixing a broken peg
TrainLab Pegbones are a 5-piece pack of replacement pegs built to fix the broken connector on an otherwise good piece of wooden railway track. The pack fits standard wooden gauge across BRIO, Thomas Wooden Railway, Melissa & Doug, IKEA LILLABO, and Bigjigs.
TrainLab Pegbones pros:
- Fixes a broken peg instead of replacing the whole piece of track
- Fits standard wooden railway gauge across five major brands
- Ships as a 5-piece pack, enough for several repairs in one order
TrainLab Pegbones cons:
- Only replaces the peg — it won't bridge to a different track system like TrackMaster or Plarail
- Five pieces can run out fast on a heavily-used layout
- Only repairs wooden tracks with an inserted peg.
Best for: parents fixing a broken peg on wooden railway track that's otherwise in good shape. Verdict: Buy.
“Fix the broken peg instead of throwing the track away.”
2. Dog Bone Connectors for wooden railway track: best for restocking general spares
This 5-piece pack is a general-purpose dog-bone connector for any standard female to female wooden railway connection. It fits BRIO, Thomas Wooden Railway, Melissa & Doug, and IKEA LILLABO on both ends.
Dog Bone Connectors pros:
- Works on any standard wooden railway joint, not just a repair
- Fits major wooden-gauge brands on both ends
- 5-pack covers multiple joins on a bigger layout
Dog Bone Connectors cons:
- Same wooden gauge only — won't bridge to TrackMaster, Plarail, or Take-n-Play plastic track
- Doesn't address a broken peg the way the Pegbone pack does
Best for: parents who want spare connectors on hand for general track building, not one specific repair. Verdict: Buy.
3. Female-to-Female Wooden Railway Track Connector: best for two sockets facing each other
This pack of 2 dog bones solves a specific, common layout snag: two pieces of wooden track that both end in a female socket with no peg between them to join them.
Female-to-Female Connector pros:
- Solves an exact, common layout problem: socket meeting socket
- Only 2 pieces to keep track of — simple and small
- Fits standard wooden gauge across major brands
Female-to-Female Connector cons:
- Only 2 pieces per pack, thin for anyone managing more than one dead end
- Doesn't help across brands that use a different gauge, like TrackMaster or Plarail
- Not a repair part for a broken peg
Best for: the exact moment two wooden track pieces face each other with sockets on both ends. Verdict: Buy if you hit that exact snag; skip if you need general spares.
4. Cross Track Connector for wooden railway: best for expanding into a junction
This 5-piece pack turns a dead-end into a four-way junction for standard wooden railway track, letting an existing layout branch instead of forcing a purchase of new track sections.
Cross Track Connector pros:
- Expands a layout's routing without buying new track sections
- Fits standard wooden gauge across BRIO, Thomas Wooden Railway, Melissa & Doug, IKEA LILLABO, and other wooden brands
- Five pieces let a builder add multiple junctions in one layout
Cross Track Connector cons:
- Adds routing choices that can overwhelm a toddler still learning a basic loop
- Doesn't repair a broken peg or bridge to plastic track systems
- Better suited to a bigger layout than a starter train table
Best for: parents expanding an existing wooden layout into a bigger, branching track plan in 2026. Verdict: Buy for bigger layouts; wait if the table is still small.
How we ranked
Every pick above got measured against the same questions: does it fit the wooden gauge you already own, does it solve the exact failure — broken peg, missing spare, or two sockets facing off — how many pieces come in the pack relative to a typical layout, and whether personalization actually matters for the use case. None of the five items compete for the same job. A parent looking for one fix should land on exactly one row in the table above.
Which wooden train track replacement pegs should you choose?
Grab the TrainLab Pegbones first if a single broken peg is the reason a favorite piece of wooden track is sitting in the toy bin instead of on the table. Building out a bigger layout or restocking general spares points toward the Dog Bone Connectors 5-pack instead. If two pieces of track are staring at each other with sockets and no peg in between, the Female-to-Female Connector solves it in two pieces flat. Save the Cross Track Connector for a layout ready to branch into junctions, and reach for the Personalized Dog Bones when the piece is headed toward a gift box in 2026.
FAQ
What's the best replacement peg for a broken wooden train track in 2026?
TrainLab Pegbones are the best wooden train track replacement pegs for 2026 because they fix a single broken connector without replacing the whole piece of track. The 5-piece pack fits standard wooden railway gauge across BRIO, Thomas Wooden Railway, Melissa & Doug, and IKEA LILLABO.
Are wooden train track connectors interchangeable between BRIO and Thomas Wooden Railway?
Yes, BRIO and Thomas Wooden Railway both use the same standard wooden peg-and-socket gauge, along with Melissa & Doug, IKEA LILLABO, and Bigjigs. A TrainLab connector sized for standard wooden railway works across all of them.
How many replacement pegs come in a TrainLab pack?
The TrainLab Pegbones pack ships with 5 replacement pegs. Other TrainLab connector packs on this list come in 2-piece, 5-piece, and 6-piece counts depending on the product.
Can a dog bone connector fix a track piece with a broken peg?
A dog bone connector joins two track pieces at their sockets, but it doesn't replace a snapped peg on the track piece itself. For a broken peg, a dedicated pegbone repair pack is the right fix.
What's the difference between a dog bone connector and a female-to-female connector?
A standard dog bone connector joins a male peg end to a female socket end. A female-to-female connector is built specifically for two track pieces that both end in a socket, with no peg on either side.
Do personalized track connectors work the same as regular ones?
Yes, personalized dog bone connectors function as real wooden railway connectors while adding a child's name to the piece. They fit the same standard wooden gauge as unpersonalized connectors.
How do I know if my track needs a peg replacement or a full connector?
If the track piece itself has a snapped or missing peg, you need a pegbone repair pack. If the track piece is intact but you're missing the connector between two pieces, a dog bone connector solves it instead.
Will these connectors work with Melissa & Doug or IKEA LILLABO track?
Yes, Melissa & Doug and IKEA LILLABO both use the standard wooden railway gauge, so TrainLab connectors and pegbones sized for wooden railway track fit both brands.
One last thing
Most parents assume a cracked peg means the whole piece of track is done. It usually isn't — the peg is a small, separate part from the plank and the paint, and a 5-piece pegbone pack keeps that piece in play in 2026 instead of in the trash.
