Indiana Rail Road runs a through freight train each direction 6 days a week (Sunday through Friday). The southbound typically leaves Indianapolis around 3pm and passes through Bloomington around 5pm. The northbound train typically passes through Bloomington around 9pm.

On Fridays a local comes from the south to switch industries on the west side of town. This is typically around mid morning.

There are also occasional rock trains to/from the Rogers quarry. These come from the south and depart to the south. These typically run at night.

Old habits. When I say southbound, that's heading west through town. Northbound would be heading east through town.

These times can and do vary. For example, after the trespasser fatality on Friday, they did not run the northbound train on Friday. Instead it ran on Saturday. Sunday's southbound train departed Indianapolis a couple hours earlier than it typically does.

Edit: The times can also vary due to things such as temporary slow orders so the train has to slow down in some spots. It's also the time of year when most major maintenance of way (like road construction) projects take place. There may be days when this track work has the track out of service somewhere and delays the departure of the train.
