Combining BRIO wooden railway with Thomas trains means matching two different track ends, and no single "universal" adapter covers every Thomas track generation. Best overall: TrainLab Adapter for Take-n-Play to Wooden Railway with Dog Bones. Best for Thomas Wood 2018 sets: TrainLab Adapter 2pk for Thomas Wood 2018 to Wooden Railway. Best for the newest TrackMaster Easy Connect trains: TrainLab Adapter 2pk for TrackMaster Easy Connect to Wooden Railway. Best repair/budget pick: TrainLab Dog Bone Connectors for Wooden Railway Track, 5pc.
- TrainLab's Take-n-Play to Wooden Railway adapter is the best overall brio train track adapter for mixed collections in 2026.
- Thomas track has shifted through at least four connector generations since 2009 - match the year before you buy.
- BRIO track is standard wooden railway, so any 'wooden railway' adapter works with BRIO, Thomas Wooden Railway, and Melissa & Doug.
- Dog bone connectors are the cheapest fix when a BRIO peg snaps, not a full adapter swap.
- Personalized wooden railway connectors exist for BRIO-compatible sets if you want a named gift piece.
Why this matters
BRIO track is a standard wooden peg-and-hole design, and so is Thomas Wooden Railway, Melissa & Doug, and IKEA LILLABO - which is why parents assume everything wooden just fits. The trouble starts when a kid also owns Thomas & Friends plastic sets: Take-n-Play, TrackMaster 2009 (brown), TrackMaster 2014 (gray), Thomas Wood 2018, or the newer TrackMaster Easy Connect line introduced in 2026. None of those plastic connectors mate with a wooden peg without a track adapter built specifically for that pairing.
Buying the wrong adapter means a piece that either doesn't seat or falls apart mid-play. This guide ranks six TrainLab adapters by the exact BRIO-to-Thomas pairing each one solves, so you order the right part once instead of three times.
What makes the best BRIO train track adapter
- Exact generation match - the plastic side must name the specific Thomas system (Take-n-Play, TrackMaster 2009, TrackMaster 2014, Thomas Wood 2018, or TrackMaster Easy Connect)
- True wooden railway fit on the other end - a snug peg-and-hole connection that works with BRIO, not a loose approximation
- Pack size for real layouts - single dog bones for spot repairs, 2-packs for adapter joints, 5-6pc packs for whole-track rebuilds
- Simple parent identification - color coding or clear product naming so you don't have to guess from a photo
- Value per connection point - price per piece matters less than getting the right piece the first time

1. TrainLab Adapter for Take-n-Play to Wooden Railway: best for mixed BRIO and Take-n-Play collections
This Take-n-Play to wooden railway adapter joins Thomas & Friends Take-n-Play plastic track on one end to standard wooden railway track on the other, with dog bones included so the BRIO-style side seats correctly instead of wobbling. It's the pairing most parents search for first because Take-n-Play sets are the most common starter Thomas kits sold alongside BRIO starter sets.
Take-n-Play to Wooden Railway pros:
- Dog bones included, so you're not buying a second part separately
- One of the most common BRIO-plus-Thomas pairings, so it solves the problem most parents actually have
- Straightforward for a preschooler to press together during play
Take-n-Play to Wooden Railway cons:
- Only fits Take-n-Play plastic track, not TrackMaster of any generation
- Doesn't help if the Thomas collection is older Learning Curve stock
Best for: parents combining a BRIO wooden set with a Take-n-Play Thomas starter kit. Verdict: Buy.
2. TrainLab Adapter 2pk for Thomas Wood 2018 to Wooden Railway: best for newer Thomas Wood sets
Thomas Wood (2018) track looks compatible with BRIO on sight, but the peg spacing and hole depth don't actually interlock. This Thomas Wood 2018 to wooden railway adapter connects 2018 Thomas Wood track on one side to standard wooden railway track - BRIO, Thomas Wooden Railway, or Melissa & Doug - on the other.
Thomas Wood 2018 pros:
- Solves a pairing many parents don't realize needs a part at all
- Works across BRIO, Thomas Wooden Railway, and Melissa & Doug on the wooden side
- Sold as a 2-pack, enough for two junction points on a typical layout
Thomas Wood 2018 cons:
- Doesn't touch plastic TrackMaster systems
- Two pieces won't be enough for a large multi-loop layout
Best for: families who bought a 2018-era Thomas Wood set expecting BRIO compatibility. Verdict: Buy.
3. TrainLab Adapter 2pk for TrackMaster Easy Connect to Wooden Railway: best for the newest 2026 trains
Mattel changed the TrackMaster connector again with the Easy Connect line, and this TrackMaster Easy Connect to wooden railway adapter bridges Fisher-Price TrackMaster Easy Connect (2026) plastic track to standard wooden railway track. If your child got a brand-new Thomas train this year, this is almost certainly the part you need to run it on a BRIO loop.
TrackMaster Easy Connect pros:
- Covers the newest 2026 TrackMaster connector, which older adapters don't fit
- Wooden side fits BRIO directly, no extra dog bones needed
- Keeps a brand-new train from sitting unused next to an existing wooden layout
TrackMaster Easy Connect cons:
- Useless if your Thomas track is the older 2009 or 2014 TrackMaster generation
- Being the newest system, fewer secondhand track pieces exist to expand a layout around it
Best for: parents with a 2026-model Thomas train and an existing BRIO wooden layout. Verdict: Buy.
4. TrainLab Adapter for Learning Curve Thomas to Wooden Railway: best for older secondhand Thomas track
Learning Curve made Thomas & Friends track before Mattel's TrackMaster era, and a lot of it still circulates through hand-me-downs and thrift stores. This adapter connects Learning Curve Thomas & Friends track on one side to standard wooden railway track on the other, meaning a BRIO set can absorb an older Thomas collection without replacing anything.
Learning Curve pros:
- Covers a discontinued system that otherwise has no easy fix
- Extends the life of hand-me-down or secondhand Thomas track
Learning Curve cons:
- Narrow use case - only relevant if you actually own older stock
- Doesn't bridge to any current TrackMaster generation
Best for: grandparent hand-me-down Thomas sets meeting a newer BRIO collection. Verdict: Buy if you own Learning Curve track, otherwise Skip.
5. TrainLab Dog Bone Connectors for Wooden Railway Track, 5pc: best for repairing BRIO track itself
Sometimes the problem isn't a different brand at all - it's a snapped peg on an existing BRIO piece. This wooden railway dog bone connector 5-pack is a spare-parts pack rather than a cross-brand adapter, fitting standard wooden railway track on both sides: BRIO, Thomas Wooden Railway, and Melissa & Doug included.
Dog Bone Connectors pros:
- Five spares in one pack, enough for several repairs before running out
- Fits BRIO, Thomas Wooden Railway, and Melissa & Doug without needing to identify a specific generation
- Cheapest fix for a broken peg compared to replacing a whole track piece
Dog Bone Connectors cons:
- Doesn't add any new cross-brand compatibility - it's a repair part, not an adapter
- Not useful if the actual problem is a plastic-to-wood mismatch
Best for: any parent whose BRIO track has a cracked or missing peg. Verdict: Buy.
6. TrainLab Bridge Adapter for DUPLO-Type Blocks to Wooden Railway: best for block-and-train crossover play
This is the one item on the list that isn't solving a Thomas problem at all - it connects DUPLO-type large building blocks on one side to standard wooden railway track on the other, and it's the only adapter here with a personalization option for a child's name.
DUPLO Bridge pros:
- Only pick on this list that mixes building blocks into a BRIO layout
- Personalization option makes it a distinct gift item, not just a functional part
DUPLO Bridge cons:
- Doesn't solve any Thomas-to-BRIO pairing
- Niche use case if your child doesn't already build with large blocks
Best for: a BRIO layout that also needs to connect to a DUPLO-style block set. Verdict: Buy if block crossover play matters, otherwise Skip.
How we ranked
Each adapter above was scored against the five criteria: exact generation match, true wooden-side fit, useful pack size, clear identification, and value per connection point. Items ranked higher solve a pairing more parents search for - Take-n-Play and Thomas Wood 2018 are the most common BRIO crossovers in 2026 - while the DUPLO bridge and Learning Curve pieces sit lower because they solve narrower problems.
Which BRIO train track adapter should you choose?
If you don't know your Thomas track's exact system, check the connector shape before ordering: Take-n-Play snaps flat, TrackMaster clips with a raised tab, and Thomas Wood 2018 looks wooden but isn't peg-compatible with BRIO on its own. For most parents combining a BRIO starter set with a Thomas & Friends kit bought in the last few years, the TrainLab Adapter for Take-n-Play to Wooden Railway is the default buy. If the Thomas train is brand-new in 2026, go straight to the TrackMaster Easy Connect adapter instead, and keep a pack of dog bone connectors on hand regardless - BRIO pegs snap eventually, and that's the cheapest fix in this whole guide.
FAQ
Is BRIO track compatible with Thomas trains?
BRIO track uses the same standard wooden peg-and-hole design as Thomas Wooden Railway, so wooden pieces from both brands connect directly. Plastic Thomas systems like Take-n-Play, TrackMaster, or Thomas Wood 2018 need a dedicated track adapter to join a BRIO layout.
What is a brio train track adapter used for?
A brio train track adapter joins BRIO's standard wooden railway connector to a different track system - most often a plastic Thomas & Friends system like Take-n-Play or TrackMaster. It lets a family run trains from two brands on one layout instead of buying a second set of track.
How do I know which Thomas TrackMaster generation I have?
Check the connector color and shape: TrackMaster 2009 track is brown, TrackMaster 2014 track is gray, and TrackMaster Easy Connect launched in 2026 with a different clip design. Matching the generation correctly matters more than matching the train model itself.
Do dog bone connectors work between BRIO and Thomas Wooden Railway?
Yes, dog bone connectors fit standard wooden railway track on both sides, which includes BRIO, Thomas Wooden Railway, and Melissa & Doug. They repair a broken peg or join two wooden pieces, but they don't bridge to plastic Thomas systems.
Can I combine BRIO with Take-n-Play Thomas trains without an adapter?
No, Take-n-Play plastic track and BRIO's wooden peg system don't interlock without a dedicated adapter. A Take-n-Play to wooden railway adapter with dog bones included solves this pairing directly.
Is Thomas Wood 2018 track the same as BRIO track?
They look similar but aren't interchangeable - Thomas Wood 2018 track needs its own adapter to connect to BRIO's standard wooden railway peg spacing. A dedicated Thomas Wood 2018 to wooden railway adapter fixes the mismatch.
What track adapter works with the newest 2026 Thomas trains?
Trains running on Fisher-Price's TrackMaster Easy Connect line, introduced in 2026, need a TrackMaster Easy Connect to wooden railway adapter to run on a BRIO layout. Older TrackMaster adapters from 2009 or 2014 won't fit this newer connector.
One last thing
The Thomas & Friends track lineup has changed connector shape four separate times since 2009 - brown TrackMaster, gray TrackMaster, Thomas Wood, and now Easy Connect in 2026 - which is exactly why a single "universal" BRIO adapter doesn't exist and never will. Check the connector on the specific piece your child owns before ordering, not just the train model on the box.
