If you hadn't noticed already, the train doors at Memorial Park have been jazzed up.

Local artist Jan Morrison has taken the blank canvas that was six tunnel doors and created an interlocking masterpiece of a story.

'Three of the doors – the front three – are based on a steam engine part. What I've done is I've incorporated aspects of fantasy to delight the public, particularly children,” says Jan, who spent a few months out painting the new doors.

'Each one has a pair – so if you can imagine, the train goes in a tunnel and comes out a tunnel, so the door that goes into the tunnel has the engine part and where it comes out of the tunnel the design on that door swings aside and reveals a little scene.

'And that's the fun thing – if any kids were so inspired they could track the doors back to each other and see a little scene happening.”

But it's not Jan's first piece of public art. The artist says she enjoys working around the Bay because people are so friendly.

'It always is [an enjoyable process] when I'm painting around Tauranga because the public comes up and comments and gives me the thumbs up.”

Other notable works include the continual touching up of old Humpty Dumpty in Memorial Park.

In fact, Jan recently gave the egg a bit of a facelift – using more durable paint.

'Because Humpty Dumpty is about 40 years old, we're hoping these polyurethane paints will last him another 40 years.

'It's because the children love him so much and they're always climbing all over him and the paint is wearing off.”
