Quilt - Ride a Train!

Mal's quilt is new this year.  Beepa (Grandma) of the Forest made it for his birthday.  He loves it so much.  Trains are one of his all time favorite things in the world.  This baby is red gingham with a central panel of a diesel and a steam train.  The diesel has a little plate on the front where Wendy quilted "MAL" for him.  She quilted everything by hand.  She puts an amazing amount of time into her quilts.  Above and below the panel, are two rows of triangles.  I don't know what the pattern is called.  I googled it and didn't see a single quilt with just rows like this.  If you know of a name for it I'd love to know.
