So I typed this request into MS Copilot not expecting much. “Create a g scale model railway layout with two loops”. This is what it came up with:

Here’s a practical G‑scale (1:22.5–1:29) model railway layout featuring two continuous loops, suitable for a garden or large indoor space. I’ll keep it flexible so you can adapt it to your available area in Chelmsford.

Concept: Double‑Loop Garden Railway

Overall Idea
  • Two independent continuous loops:
    • Outer loop: mainline passenger or express running
    • Inner loop: freight, shunting, or branch‑line operations
  • Crossovers allow trains to move between loops.
  • Designed for reliable running with gentle curves and gradients.
Recommended Space
  • Minimum: 4.5 m × 3 m (15 ft × 10 ft)
  • Ideal: 6 m × 4 m (20 ft × 13 ft)
  • Track radius assumptions:
    • Outer loop: R3 / 1500 mm radius or larger
    • Inner loop: R2 / 1200 mm radius
(These suit LGB, PIKO, and most G‑scale stock.)

Key Features


1. Outer Loop – Main Line
  • Large-radius curves for smooth running
  • Passing station with:
    • Platform
    • Run‑round loop
  • Scenic focus: embankments, bridges, tunnels
2. Inner Loop – Freight / Branch
  • Smaller radius but still G‑scale friendly
  • Goods yard with:
    • 2–3 sidings
    • Small goods shed
    • Engine spur
  • Optional short gradient (max 2–2.5%)
3. Crossovers
  • Two manual or electric points connecting loops
  • Enables:
    • Continuous running
    • Operational interest
    • Multiple trains at once

Track Components (Typical)
  • Track: LGB or PIKO brass (excellent for UK weather)
  • Points:
    • 2 × loop crossovers
    • 2–3 × yard points
  • Power:
    • Track power (analogue or DCC), or
    • Battery/RC for outdoor reliability

Scenery & Structures


  • UK‑inspired or European alpine theme works well
  • Raised beds with:
    • Dwarf conifers
    • Ground‑cover plants (thyme, sedum)
  • Weather‑resistant buildings (resin or treated wood)

Expansion Options
  • Add a third elevated branch
  • Engine shed with servicing area
  • Hidden storage loop
  • Live steam‑friendly clearances

Next Steps

If you like, I can:
  • Customise this to your exact garden or room size
  • Produce a precise track list (LGB or PIKO)
  • Create a visual layout image
  • Design it specifically for live steam

What space do you have available, and will this be indoors or outdoors?

In about 45 seconds it also rendered the attached image! I just need to figure out how to get it to build it for me!

Reminds me that when I've added my little extension, I'll need to make a new track diagram. I'm not sure I have the patience to use something like Visio any more, so I thought of doing a freehand sketch and asking AI to tidy it up. Something for a wet weekend, perhaps.
 
I think AI looked into the swirl on top of its flat white and hallucinated a railway.

I particularly like the single line that leads from the end of a platform to a running line, with a locomotive shown well beyond the 'Limit of Shunt'. :rofl:

Oh a Terminator should be able to manage that.
 
Track diagram? Wassat?

I just started putting the rails down, it soon works out OK. Mind you, I don't go in for any of this track geometry stuff; I worked with 8ft and 10ft radius curves, a fair bit of second hand flexi track and a good hacksaw >:)>:)

A few drills and taps of the correct size for Bachmann/Aristo fishplates, and a load of Hillman clamps that came with the second hand LGB flexi.


Seeeemples ;);)

Ah, and a photo of Skagway junction :nod:
