The Transport Department has revealed the logo and livery for the new national rail body, representing a major advance in its policy to take the railways into public ownership.
The updated design showcases a patriotic colour scheme to represent the national flag and will be applied on GBR trains, at railway stations, and across its online presence.
Significantly, the symbol is the well-known double-arrow design historically used by the national rail network and first created in the 1960s for British Rail.
The rollout of the branding, which was created by the department, is expected to occur in phases.
Passengers are set to begin seeing the newly-branded trains on the network from the coming spring.
Throughout the month of December, the visuals will be showcased at prominent railway stations, such as London Bridge.
The Railways Bill, which will enable the formation of Great British Railways, is presently moving through the House of Commons.
The administration has said it is renationalising the railways so the service is "run by the passengers, operating for the passengers, not for corporate interests."
Great British Railways will consolidate the running of train services and tracks and signals under one umbrella body.
The government has stated it will combine seventeen various bodies and "reduce the frustrating red tape and lack of accountability that continues to plague the railways."
The rollout of Great British Railways will also feature a new mobile application, which will enable users to see timetables and reserve tickets without surcharges.
Accessibility travellers will also be able to use the application to book help.
A number of train companies had earlier been taken into public control under the outgoing administration, such as Southeastern.
There are now 7 train operators already in public hands, representing about a third of rail travel.
In the past year, South Western Railway have been nationalised, with further franchises likely to follow in 2026.
"The new design is more than a cosmetic change," commented the Transport Secretary. It symbolises "a new railway, leaving behind the problems of the previous system and focused entirely on providing a proper service for the public."
Rail figures have welcomed the focus to improving services.
"The industry will continue to work closely with all stakeholders to facilitate a smooth changeover to GBR," a senior figure added.
