“The Railway Children,” featuring Izaak Cainer, Rozzi Nicholson-Lailey and Beth Lilly, on The Shows Must Go On and BroadwayHD online. Evoking the bygone era of British high society and the heyday of travel by steam train, “The Railway Children,” is a family-friendly event with a decidedly English flair and a truly unique staging that should satisfy audiences of all ages. As an American, I had to do a little digging about The Railway Children, a beloved children’s book in Great Britain. Published in 1906, author Edith Nesbit combined intrigue and adventure into a story about three privileged youngsters who work to solve the mystery of their missing father while befriending a bevy of colorful characters at the local railway station near their new home in Yorkshire. Apparently the book and the many film and television adaptations of “The Railway Children” are commonly revered all over the United Kingdom. The stage adaptation originated in 2008 at the York Theatre Royal, and has been re-staged several times, quite memorably at the National Railway Museum in York, featuring a vintage steam locomotive! The production from 2016 was recorded in performance and is the current selection on The Shows Must Go On!
