Advancing the punners

Here's a list of train puns that I have used in actual conversations since the beginning of my trip:

"I'm sorry, I'll try to conduct myself a little more professionally."

"I'm not railing against the use of all automobiles."

"Did I get you off track? Did you lose your train of thought?"

"I like how you express yourself."

"Maybe we can engineer another time to meet up."

"I'm not really trained in that field. You know, not my line of work."

As the trip goes on, and more puns are discovered I will add them to the post.

*Told to me by Blue Derkin: "How do you gauge what the best train lines are?"
