UPDATE:

Here's my cake all finished and ready for my little guy.  He loved it!

It's my sons 2 year old birthday this week. He loves trains. I found a great tutorial from Betty Crocker for a train cake, but I like this picture of a cake that a real person made. :)  I like her changes to the Betty Crocker way.

Go here to see this train off of My Sisters' Cucina...

She has a link on her site to the Betty Crocker/howdini Video. :)
