An ingenious method was used in the early days of mixed gauges on the Great Western Railway, by which narrow gauge and broad gauge trains could be sent on diverging paths without the use of ordinary switches controlled from a signalbox.

In 1987 the Penalty Units and Other Penalties Act introduced a new scheme for financial penalties. The penalty provisions in a number of Acts containing commonly occurring offences were amended to specify the fine in penalty units rather than a specific sum.
