Easy puzzle to get on train

Because of my upcoming birthday I decided to make a train. Before you can get on, you'll have to complete this puzzle.

The GA's end on Friday the 13th. Hope you're the lucky one!

To celebrate I have made this piece of poetry:

Do you also feel that urge
Possibly you do
Or are you one of those good guys
Will you scratch that itch
Before time runs out

Have a go at poetry yourself or just bump the thread :).
