Kato HV1 HO UNITRACK outer oval expansion
HO scale

When to choose it
The HV1 adds an outer oval around a compatible inner HO UNITRACK route. It is useful when you want a second continuous path and can reserve the extra footprint for the larger curve.
The package identifies R730 and shows an outer-track expansion. Compare the exact pieces and layout dimensions with the inner route you already own before adding a second loop.
