Smoke Hill has been dormant for years, but one day when Ivor sees smoke rising from the top, what do you happens next?

Idris is a small Welsh dragon and has made friends with Ivor and Jones.

There have been reports of sudden burn marks around Llaniog. Could Idris be responsible?

Idris and his friend, Olwen, help Mr. Thomas at his fish and chip shop.

The dragons have disappeared and the Antiquarian Society have arrived. What will Ivor and Jones do?

Ivor, Jones and Evans are in a spot of pigeon trouble.

One day, Ivor the Engine spots an elephant on the tracks after retrieving some naughty pigeons.

Alice the elephant is poorly and has proven to be a quite difficult patient indeed.

Roll up! Roll up! The circus has come to town with free tickets for all!

Winter has arrived once again. Ivor is having a lovely time in the snow. With a winch attached to his front, he is pulling the children on sledges up the hill. He pulls too many at a time and ends up wheel-deep in the snow. Various rescue attempts prove futile.

Smoke Hill has gone cold. A disaster for the dragons!

Jones goes over to the Society for help.

The problem with Smoke Hill is solved in a quite responsible way, but what?
