All aboard for Windsor, where it's currently all about the Duke and Duchess of Sussex's new baby, Archie. This event, however, has plenty to excite train geeks and history buffs as well as royal watchers.
For years, UK Rail fanatic David Buck has been collecting and running steam train engines and carriages on tracks laid across his Windsor farm. At the end of last year, he bought the Steam Dreams Rail Co, which runs tours on the Flying Scotsman and as of June, the company is running the Royal Windsor Steam Express, touting it as "the first regular steam train service in modern history from London Waterloo to Windsor".
It's the same route early royal trains took to transport the royal family.
The service offers three classes of travel and two levels of dining. The luxurious "Pullman Style Dining" option takes place in a dining carriage decorated in the style of a bygone era and can include a champagne breakfast or brunch on the outwards journey and a four-course meal, with wine, on return.
Also new is the Sunset Steam Express, which will leave Waterloo at 6pm for a four-hour round-trip heading south across the suburbs of London, through the historic cathedral town of Guildford before taking the steep climb through the Surrey Hills, descending into Holmesdale and then heading back to Waterloo via the market towns of Dorking and Reigate. Dinner will be served en route.
Both services, which will run from June 4 to September 3, are pulled by Buck's own B1 Class Locomotive, the Mayflower, which was built in 1948 and sports its original British Rail apple-green livery.
For the Windsor service, tickets start at £35 (about $64) and up to £85 (about $156) for the Pullman Style Dining.
The Sunset Dining service starts at £99 ($182) a person; a private compartment for four costs £449 ($826). A standard ticket is £49 ($91).
Standard ticket-holders on both trains can access restaurant cars and picnics are welcome.
