Her great-great-grandmother, Queen Victoria, was the first ever British royal to take a train journey.
Today, 175 years later, the Queen along with the Duke of Edinburgh recreated that very same trip on the Great Western line travelling from Slough in Berkshire to Paddington.
It's fair to say, things have changed a bit since 1842.
As Mel Bloor reports.
Mel spoke to Isambard Thomas and Mark Hopwood from Great Western Railway.
The Queen will this week mark the 175th anniversary of the first train journey made by a British monarch.
On 13 June 1842, Queen Victoria made the trip from Slough to Paddington, writing in her journal afterwards that it was "delightful and so quick".
The Queen and the Duke of Edinburgh are due to embark on the same journey on the day of the anniversary- this time as the first passengers on one of the region's new Hitachi high speed trains.
Joining them will be two descendants of pioneering railway engineers Isambard Kingdom Brunel and Sir Daniel Gooch.
Mark Hopwood, managing director of Great Western Railway, said he was delighted the Queen was marking "this historic anniversary".
"This occasion marks a very special moment in the history of the Great Western Railway," he said.
The Queen is expected to name a train as part of the celebrations.

Mears was given just a 5% chance of survival in 2009 after suffering a ruptured spleen but overcame his illness to become an olympic champion.

As a young princess she enjoyed riding in Windsor Great Park - something she still does today.
The Queen owns and breeds thoroughbreds. Those close to her say horse racing is when she really relaxes. Penny Silvester has been talking to the Queen's Racing Advisor, John Warren, about why her affection for these animals runs so deep.
