I have a train cake to do for a 1 year old and they want on top of the cake to be some kind of train topper and want to stick the pic of there son on it!

I'm doing a cake where I'm showing the train going across and reaching the top where I already have a # 1 topper.
Can anybody guide me to direct me to do a fondant train topper????

Any help is appreciated!

I can't help you with a fondant topper but I did a cake with a train and made it on a cutout sugar cookie and iced it with buttercream.
