Previously, services had reduced to a half-hourly frequency after 7.30pm.

On Sundays, the service reduces to hourly operation in both directions.

Extra services run at peak times, and the service reduces to hourly operation in the evenings.

On Sundays, the service reduces to hourly operation in either direction.

Thus the impression was created that social services would gradually reduce inequalities in British society.

Our second tentative conclusion is that social services may have reduced people's subjective sense of inequality.

Grouping services into functional layers reduces the impact of change.

After 20.00, the service reduces to one train every hour in each direction.

Cheaper services would reduce the cost of production and consumption.

The service took 12 hours, later reduced to 10 hours, and ran two or three times weekly.
