Nickel silver rail joiners for Peco Streamline Code 75 track, supplied in a pack of 24. These are the standard conductive joiners — they hold the rail ends in alignment and carry current across the join, which is what keeps a layout running reliably as track ages and oxidises.

Code 75 is Peco's finescale rail height, matching scale rail proportions rather than the taller Code 100 used in most starter systems. Joiners are height-specific, so Code 100 joiners won't seat correctly on Code 75 rail and vice versa. Check which code your track is before ordering.

Nickel silver is used rather than steel because it doesn't rust and its oxide remains conductive, so joints keep working where a plated steel joiner would eventually go high-resistance.

Fitment

Suits Peco Code 75 flat bottom rail, including:

• SL-100F, SL-102F, SL-104F, SL-106F — 00/H0 Fine Standard track systems
• SL-108F — Code 75 Bullhead track
• SL-1400 — H0m track
• SL-1500 — H0n3 track
• SL-8300, SL-8302 — Code 83 American range

These are conductive joiners

For electrical breaks — including the gaps required when using Electrofrog turnouts — you need insulated rail joiners, which are a separate part. Peco's Wiring the Layout publications numbers 4 and 21 cover where those breaks are needed.
