Railway mileposts

Old and new railway mileposts in the UK, indicating a distance of 33¼ miles from the zero point

In 1845 the Railways Clauses Consolidation Act was passed compelling the UK railway companies to provide their passengers with a means of determining the distance traveled (fares were set by distance at this time). Section 94 states:

The company shall cause the length of the railway to be measured, and milestones, posts, or other conspicuous objects to be set up and maintained along the whole line thereof, at the distance of one quarter of a mile from each other, with numbers or marks inscribed thereon denoting such distances. ^[1]

Similar laws applied in other countries. On the modern railway these historical markers are still used as infrastructure reference points. At many points the distances shown on the markers are based upon points no longer on the network, for example measured via a closed line or from a junction which has subsequently been moved. Whole mileposts are usually supplemented by half and quarter posts. Structure signs often include the mileage to a fair degree of precision: in the UK a chain is the usual accuracy. A chain is a unit of Length; it measures 66 feet or 22 yards (20 In the US and Canada, however, miles are "decimalized", so that, for example, there may be a "milepost 4. 83. "

In metricated areas the equivalent is the pointe kilometric, or pk.

On undivided highways, both sides of the milestones are used, telling the distance to the nearest cities in each direction. The head of the milestone has the highway number written on it. The side of the milestone has a number which is the sum of distances of two nearest cities in each direction from the milestone.
