The loading gauge standard is defined by 2 key rules:
- Minimum vertical (height) clearance: lowest clearance height from railhead is to be 13 bricks.
- Minimum horizontal clearance: 4 studs from inner and outer rails, with the exception of platforms (see below)
Implications for infrastructure and scenery building
We expect all mainline infrastructure such as station platforms, bridge supports, and tunnels used on LNUR displays to accommodate all vehicles on the lines built to these standards.
- Platforms – awaiting update.
- Within tunnels and cuttings, ensure ~4 stud clearance overhang from the edge of the track (i.e., 5 stud clearance from the railhead itself on either side). This will ensure longer rolling stock and locomotives can clear this section.
Don’t worry – it can take some practice to get it right, and even long term members get this wrong occasionally – it’s just trial and error and a lot of patience!
This loading gauge standard is still in use on LNUR displays.
There are no current plans to rewrite or update this standard, though individual member layouts may still use their own loading gauges. This is primarily due to many of our members’ locomotives and rolling stock being constructed to accommodate this loading gauge.
- Northern Club Layout
- Darrington Railway – the main LNUR display (2019 – 2020)
- Ambridge & Paxley Railway – whilst this display doesn’t follow the LNUR track geometry standard the landscape is still built with standard clearances in mind.
- Felpersham LEGO Railway (now retired)
The following amendments were made to this standard:
|Updated the text to match with the work on the Northern Club Layout landscape standards v1.1
|Change to the minimum required width to be allowed clearance: changed from 8 studs to 10 studs to accommodate new valves and rods, and a larger general width for locos and rolling stock being built by club members.
