Hectometre

A hectometre is a distance unit equal to 100 metres and is used in station notation. The format a+bbb.bb means full hundreds of metres before the plus sign and the remaining metres after it; for example, 2+045.50 means 245.50 m from the route start. This notation makes long routes easier to read and points easier to identify in the longitudinal profile and plan view. When checking documentation, make sure station notation is consistent in drawings and tables and that conversion to metres matches section lengths.
