It will be the 20th episode of The Tales Of Thomas and Friends Season 23.
After the snow melts, the water level in a stream near Hackenbeck rises to dangerous levels, and Percy is worried. Toby brings news that the water level is dropping, to Percy's relief. Later, Henry jokes Thomas may actually be kept at the National Railway Museum, and Annie and Clarabel are so upset Percy is late after soothing them; matters are not helped when he has to take on water at Elsbridge. Percy is later crossing the bridge when he hears an ominous creaking, and no sooner has he crossed it than it is swept away. The line is closed while the bridge is mended, and although things are back to normal after its rebuilding, Percy has always been careful while crossing it.
