The Off-Peak Return is a type of train ticket used on National Rail services in Great Britain.
Typically train operating companies prevent use of this type of ticket during key commuting hours of weekday mornings and early evening, especially for services beginning or terminating in London, at which times higher fares may be charged.
The times at which an Off-Peak fare is valid are set by the relevant train operator according to various factors, from levels of peak demand on the route in question to revenue maximisation.
The simplest apply a simple blanket time period to both outward and return journeys; more complex validity codes may apply different restrictions to outward and return journeys, or combine general validity periods with train-specific exemptions or exclusions.
Passengers are entitled to pause and resume their journey at any point and any number of times unless the ticket's validity code specifically prohibits this.
