Train set oval with a passing loop
A passing loop on the outside of a 1st radius oval. One train can wait in the loop while another runs round, which makes operating feel like a real railway instead of watching one train go in circles.

Good to know
- The loop uses Hornby's standard 67mm track spacing, so it lines up exactly with the main line.
- This one is a tight fit on a 6 × 4 board, with only a few centimetres spare at each end. Measure your board before buying.

Checked with the First Radius geometry engine: every joint meets, the track fits the board with the space shown, and no tracks overlap. Figures use Hornby's published setrack geometry; real track has a millimetre or two of play.
