planespotters be like "yup, thats a plane alright"

My business is on a fairly busy railroad track. Our parking lot is really close to the tracks. We regularly have people show up to take pictures of trains. Union pacific has acquired lots of other railroads so you get lots of trains and paintjobs coming through.

Here is the thing though, they always show up like 1 minutes before the train, take their pictures and leave. But how do they know when the train will be there? My secretaries husband is a conductor for the trains and they don't even have the information internally exactly when a train is going to hit a certain crossing since the trains only have a scheduled time when the crew shows up, not a designated time to leave

Every time i notice one of these train neurodivergents, they are already leaving and i have never gotten to ask
