The Virtual Museum of Canada has a neat activity called The Train Messenger. It would be accessible to English Language Learners of all levels.
In it, you can design a train and the scenery, write a message about it, and then email the url so it can be posted on a blog or online journal. While you’re making your train, you can also read (in simple English) information about the types of rail cars and locomotives you’re deciding to use.
I’ve placed the link on my Examples of Student Work page under Student Train Messages.
