Fantastic work, Mmachi! Your idea for The Family Train is a speedy one at 50 mph – that's faster than my homework when I'm in a rush! 🚄 With five carriages, there's plenty of room for everyone to enjoy the ride. Have you thought about adding any fun features inside the carriages, like a snack machine or a games area for the passengers? Keep those creative wheels turning, and who knows where your imagination will take you next! 😊
