Unscheduled flag stops on the transcontinental railroad?

From: "Gunnar Bron" ultra.cole2sworld@gmail.com

Hi I am 17 year old Junior at Memorial High School in Manchester, NH. I have been given a project where I create my own journey on the Transcontinental Railroad. All is going well except I could not find a answer to this question.

Would you know if the railroad would stop if I wanted it too, like what I was thinking is in the story I am asking the conductor to stop at the next small town for me and my family to get out and walk around and check out what is there. Would trains of this time do that for me? ...
