Child's Train Jumper

I’m looking to knit a jumper for my 6 mth old daughter with steam trains on it - my husband is very keen on trains! I can’t seem to find any patterns here in England though. Does anyone have any recommendations where to start looking?

I’m happy to knit something in a larger size and wait for her to grow into it if necessary - I’m quite a new knitter so something complicated would take time!

Many thanks

Here is a chart of a train you could add to a pattern.
