Chugging along on a 90 year old train

They are still quite a lot of steam trains around UK nowadays, a legacy from the old days, often kept alive by groups of passionate volunteers. They are popular with holiday makers particular with families with small children. I mean which child doesn't like riding on the trains? The North Bay Heritage Railway is one of these. The line is called heritage, because it dates back to 1931, over 90 years ago!! And I reckon it's even more popular with children because it's a miniature railway.
