HO stands for "Half O" as in "O" gauge model railways. The odd scale of 1/87 comes from model railway gauges being set in millimetres which leads to odd modelling scales when converted over to imperial scales. OO, or "Double O" is 1/72nd to 1/76th scale but the actual track gauge for OO is exactly the same as HO. It's because the bodies of OO model railways are technically too big (overscale) for the gauge but the scale of 1/72 - 1/76 is based on the size of the bodies.
As a result, HO model trains are therefore proportioned better and more accurate to the real thing but are noticeably smaller than OO trains.
