One of my favorite things to do is travel. I love experiencing new places and cultures!
I do too but it sometimes can be stressful. The word travail means struggle. 
Oh! I never knew that! How do you usually travel? Airplane, train or car?
I travel by air for long distances just because it's much safer than driving.
Yes, so much faster too! I don't mind flying but I'd like to try traveling by train sometime.
That's true traveling by train can be really fun and cheap too somethimes
I think it'd be a great new experience. Europe has a lot of rail systems I think. What else do you know about travel?
Well, there are two types of rail systems: light and heavy rail.
What's the difference between the two? What type of rail does a high speed train use?
They are considered heavy rail because they use heavier cars.
