4.14.24 Fleming MO - BNSF Marceline Sub Milepost 419 / CA Junction

The westbound manifest was already slowing to stop ahead when he into emergency. Sounded like there was traffic backed up on the west side of the Missouri River needing to get east so he was likely going to see several of those eastbounders before getting his turn to cross the Sibley Bridge. The conductor made the long, long, long walk all the way to the end of the train looking for a disconnected air line and not sure he ever fond it. I hung out for a while after the eastbound manifest passed waiting for him to get underway again but never resumed his journey west.
