Brand new, unused sets of Hornby OO Gauge Railway Track Expansion Pack A and B These packs are for use with a DC powered two-rail system, featuring an analogue control system. The track is in a 1:76 scale, perfect for adding to an existing Hornby OO gauge railway setup. The ready-to-go nature of the pack makes it easy for hobbyists to expand their track layout and enhance their model railway experience. Great expansions for the Hornby starter kit also listed on my profile
