Sure have. In fact, I took a look at the Mid Sodor Engines story "Closer" just now. It has been pulled off very smoothly. You can easily tell just how much pain Falcon, Stuart and Duke went through.
indeed, when the NRM engines came to the Lunar Railway to be restored and some put in a new museum as their new home, Duchess of Hamilton (or Duch by her friends) helps Pipa clear the snow.
