Gordon:Don't worry. That's just a light rail train.
The new light rail system shares the road with street traffic.
Jean:Phew! For a second there I thought we were going to collide with it.
Gordon:Didn't you see the operator seated at the front of the train?
She watches out for other drivers.
Jean:I didn't know they have operators.
I thought they were automatic.
Gordon:No, they're not like some forms of rapid transit.
Jean:I see now that they ride on tracks and are powered by overhead electric lines.
Jean:I'd like to give light rail a try.
Gordon:Really? Well, there's no time like the present.
I'll take you to the nearest stop. There's the platform over there.
Jean:But I thought you agreed to give me a ride into the city.
Gordon:And deprive you of a new travel experience? Never!
