The administration has revealed the logo and livery for GBR, marking a key advance in its strategy to bring the railways under public control.
The fresh livery uses a patriotic design to reflect the UK flag and will be used on GBR trains, at railway stations, and across its digital platforms.
Notably, the symbol is the recognisable double-arrow design presently used by National Rail and originally designed in the 1960s for the former state operator.
The implementation of the branding, which was developed by the department, is set to occur gradually.
Passengers are set to begin spotting the freshly-liveried services throughout the network from next spring.
During the month of December, the branding will be displayed at major railway stations, including Leeds City.
The legislation, which will allow the establishment of Great British Railways, is currently progressing through the Parliament.
The administration has stated it is renationalising the railways so the network is "owned by the people, delivering for the public, not for private shareholders."
GBR will consolidate the operation of passenger trains and tracks and signals under one umbrella body.
The department has stated it will merge 17 various bodies and "cut through the frustrating red tape and poor accountability that continues to plague the railways."
The launch of Great British Railways will also involve a dedicated app, which will let users to check timetables and book tickets without booking fees.
Accessibility passengers will also be have the option to use the app to request support.
Several franchises had already been nationalised under the former administration, such as Northern.
There are now seven operating companies already in public control, covering about a one-third of rail travel.
In the last twelve months, South Western Railway have been nationalised, with more anticipated to follow in the coming years.
"This is not simply a paint job," said the Transport Secretary. It represents "a fresh start, shedding the frustrations of the past and focused entirely on offering a reliable public service."
Rail figures have welcomed the government's commitment to improving services.
"The industry will continue to collaborate with industry partners to support a seamless changeover to the new system," a senior figure said.
