It is a special day for Ivor the Engine. Ever since he got his new whistle, he has been chosen to take the Grumbly District Choral Society to take part in the Eisteddfod in Llanmad.
After the festival, it's off the seaside, but Ivor is feeling left out, so he makes a plan...
Ivor has run away and nobody knows why. The search is on!
After going off without a driver the other day, Ivor takes the Grumbly District Choral Society to Tewyn Beach once again for Bank Holiday, but Jones the Steam has a surprise for the little tank engine to cheer him up.
Ivor the Engine and Bluebell the Donkey are best friends, but their friendship causes trouble for Jones and Mrs. Porty.
Dai Station isn't too pleased about Ivor's new friend, Bluebell, however when Ivor comes off the rails at the points, he soon learns just how useful she can be.
While puffing through the forest, Ivor and Jones come across a bird's nest on the railway line, so they have to find a new home for the mother bird and her chicks.
Mrs Porty shows Jones and Ivor the fox cubs in the wood near her house. As Ivor and Jones go to deliver Mrs Porty's Hat for the Institute Prize Giving, they save the fox from the fox hunt, by hiding her in the hat box.
On a cold winter's day, Jones falls into the frozen water whilst trying to re-rail the truck leaving Ivor stuck on Tewyn Lake bridge, so it's up to his friends, the birds, to save the day.
Some time after the lake fiasco, Ivor spots the fire engine while clearing snow, but then what do you think happens next?
One winter's day while taking corn bags to Mr. Pugh's Farm, Ivor spots a sheep trapped on the cliffside of the old quarry line.
There's trouble on the railway. The Merioneth and Llantisilly Rail Traction Company Limited is to be sold to the Welsh National Railway Commission as a branch line and Ivor might have to become shunter at Pontypool Roads. So it's up to Mr. Dinwiddy the goldminer and Mrs. Porty to save the railway from closure.
It's Christmas in the top left hand corner of Wales and Mrs. Porty has a parcel for Ivor which he then gives to the birds, but what could it be?
