MRSI Exhibition 2026: Dublin's Biggest Model Railway Show

The Model Railway Society of Ireland's annual exhibition is the single biggest event on the Irish model railway calendar. In 2026 it returns to a new venue — Mount Temple Comprehensive School on the Malahide Road in Dublin 3 — running the October Bank Holiday weekend, Saturday 24 to Monday 26 October.

If you only attend one Irish model railway event in 2026, this is the one.

What's New for 2026

The new venue is the headline change. Mount Temple offers more space than the previous venue, which means more layouts, wider trade-stand aisles, and easier flow on the busiest Saturday afternoon.

Irish Railway Models / Accurascale are the show's sponsors and typically use the weekend to launch new Irish-outline models. If you collect Irish prototype RTR, plan to be at the Accurascale stand on Saturday morning.

Featured Layouts

Plus dozens of other layouts from clubs across Ireland, Northern Ireland, and visiting UK clubs — covering periods from the steam era to modern Iarnród Éireann.

Trade Stands

40+ stands typically attend, including Irish Railway Models / Accurascale, Clark Railworks, MarksModels, plus UK retailers and specialist suppliers. Show-only deals are common — bring cash for smaller traders.

Strategy for Your Visit

If you only have one day, Sunday is the sweet spot — quieter than Saturday but with everything still running. Saturday morning is great if you want to catch new-release announcements, but expect crowds at Accurascale's stand.

If you can split into two days:

What to Bring

Pair with the SDMRC Exhibition

SDMRC's biennial show at Blackrock College usually runs the same weekend. Worth a visit on a different day for a different mix of layouts.
