Need some math help concerning a special train trip?

I looking to possibly do a video on the Lincoln Funeral Train for Halloween and Math isn't exactly my strong suit. Folks familiar with the train have probably also heard of the ghost stories associated with it. One particular story is about a doctor who lived in the Albany, NY area some time in the last century as the doctor is depicted driving a car in the story. He'd had to make a house call one night in late April and it was around 10:30 PM while on his way home from that call that he came to the tracks and supposedly witnessed the train. The train appeared to be traveling at 20 MPH. The story does make it clear the doctor had to travel thirty minutes from home so it wasn't in Albany he witnessed this.

For years I paid where it took place no mind, it was just that it had to happen late at night. But as I said I'm thinking of doing a video for Halloween that would feature this story and got to making a map of the route. And I found this site, http://www.lincoln-highway-museum.org/WHMC/WHMC-LF... which included times for the train's arrival in various towns. The train reached Albany April 25, 1865, but the night before seems to suggest the doctor's story happened April 24th. What I'm looking for is around what town this might have been as it arrived in Hudson at 9:45 PM then passed through Stockport, Stuyvesant, Schodack, and Castleton before arriving in Greenbush at 10:55 PM. If it was going 20 MPH that night, about what town would have been reached at 10:30?
