In a touching detail and in line with his wishes, Prince Philip’s coffin will be driven from the State Entrance of the Castle to the West Steps of the Chapel on a specially modified Land Rover he helped design himself.
Soldiers from the Corps of the Royal Electrical and Mechanical Engineers (REME) are reportedly working to prepare the special Land Rover.

The Duke, who championed British design and engineering throughout his lifetime, is understood to have had a hand in commissioning two of the vehicles some years ago.
While one will be used in his funeral procession, a second is available as a back up.

The coffin, draped in the Duke’s personal standard and with flowers, his Naval Cap and sword placed on top, will be carried from the State Entrance to the Land Rover by pallbearers from the 1st Battalion Grenadier Guards at 2.40pm.
At 2.45pm the Prince of Wales and other members of the family will walk in procession behind the coffin along a route lined with socially distanced servicemen and women from across the Armed Forces.
At the West Steps, a pallbearer party from the Royal Marines will carry the coffin up to the doors of the Chapel as a Royal Naval pipe band plays, ahead of the minute’s silence.
The Queen will be one of just 30 guests
The intimate service, conducted by the Archbishop of Canterbury Justin Welby and the Dean of Windsor David Conner will follow a military funeral procession and a national minute’s silence in his memory.
The events will take place entirely within the confines of the Castle and members of the public are being urged not to travel to Windsor or other royal residences to pay their respects, but to watch the ceremony on television instead.
In addition to the eight days of national mourning announced by the Government, starting on the day the Duke died, the Queen has approved a two-week period of royal mourning for members of her family during which they will wear black or uniform with mourning bands and only carry out engagements deemed appropriate in the circumstances.
