Prince George and Princess Charlotte visit city farm while Kate Middleton and Prince William spend night in Yukon
The royal family are making the most of their time in Canada.
While we haven't seen much of Prince George and Princess Charlotte since they landed in Victoria on Saturday, Kate Middleton and Prince William have been taking centre star every day during official appearances around the country.
But the royal tots haven't been holed up behind closed doors in their government residence, the duo enjoyed a day out at Beacon Hill Children's Farm on Wednesday with their nanny Maria Borrallo.
At the Cambridges' base in Victoria their children had been taken to the family farm, described as "providing both an educational and economical form of entertainment for the whole family", while mother and father had a night away in the old gold rush town of Whitehorse in the Yukon.
The trip was made public by Victoria Tourism, which tweeted George and Charlotte's secret escape.
Earlier in the day, the Duke and Duchess of Cambridge found themselves on the wrong side of the tracks when they made an impromptu stop to see a Canadian steam train.
After walking through clouds of steam to clamber inside the cab - and taking the chance to blow its whistle - they had to make the return journey but were left cautiously watching every step, during a visit to the tiny wilderness hamlet of Carcross in the Yukon yesterday.
The locomotive had stopped close to the end of a railway bridge that crossed a stretch of water and although the drop below their feet was not a long one, there was no rail to stop them falling.
William decided to get a closer look at the locomotive after hearing how his grandparents the Queen and Duke of Edinburgh had travelled in the last carriage of the train which was specially fitted out with a marble table for their 1959 visit.
First Nation chief Andy Carvill, 52, of the the Carcross Tagish, who hosted the royal couple's visit to his settlement, said: "The Duke asked if he could go in and they got inside the train and blew the steam whistle.
"I told them about the Queen's coach and they were pleased to hear that."
William and Kate's escapade came at the end of a day where the royal couple sent their first joint public tweet - to sign a virtual visitors' book - and it emerged that Prince George and Princess Charlotte had spent Tuesday at a petting zoo in Victoria, British Columbia while their parents were visiting the Yukon.
William and Kate's foray into the world of social media had a twist as they used old technology - in the form of a morse code telegraph machine connected to a pc - to send their virtual message during a visit to Yukon history museum in Whitehorse.
The dots and dashes were tapped out by Doug Bell, a former commissioner of Yukon, but the royal couple both held the lever down to send the tweet, posted under the Twitter account Telegraph to Tweet, which said: ''The Duke and Duchess of Cambridge, September 2016, Whitehorse Yukon.''
Kate had begun the day in Whitehorse wearing a red Carolina Herrera coat and arrived in Carcross in a cardigan coat by the designer Sentaler - a favourite of Sophie Gregoire Trudeau, the wife of Canada's prime minister Justin Trudeau.
Before they spotted the steam train the royal couple had been partway up Montana mountain learning about the Single Track to Success Scheme which has created jobs for First Nations people.
They watched a group of children cyclists being put through their paces on a course and met 11 mountain bikers who were about to tackle a 2km trail.
"Don't break anything on the way down," William told them and he added: "It's great scenery to be riding in."
The Duke went on to say: "We went to Calgary and other parts of Canada in 2011 but this is on another level. Amazing scenery."
According to Carcross legend, the mountain, known as Tselgi Shaa - Gopher Mountain - in the local language is one of four peaks in the area from which the Game Mother hung a hammock to host a celebration for her animal creations before they spread out across the land.
Later on Thursday George and Charlotte are expected to join their parents for a children's party in the beautiful grounds of Government House in Victoria.
A group of military families have been invited to share a morning with the Cambridges. The rest of the day will provide the Duke and Duchess with some private time with their children.
