Today at the Maine discovery museum of Bangor kids got a lesson on different types of trains.
Everything from steam locomotives to diesel locomotives, and how trains are different today then they were in the age of steam.
They also learned about the new steam locomotive that's being built in Ellsworth Maine.
President of the New England Steam corporation Richard Glueck said "I love steam I'm a steam guy from way back, but I love trains anyway. All trains are fun and interesting."
He says it's important for kids to know about trains because it's apart of history and a technology that built our country.
