Witness account of UFO sightings during a train ride

Summary

A man traveling by train described seeing two glowing objects, yellowish-green in color, rapidly ascending. The first appeared as a bright spot on the window, and upon closer look, it revealed itself as a ball rising quickly. After it vanished, he went to inform the other passengers, when a second object appeared. At that moment, the compartment lights were turned off, and despite their attention, they could only see the round light. There was no sign of smoke or rocket trails, and the object seemed to move gently upward along an inclined path. The witness heard no unusual noises and saw no searchlights aimed at the objects, adding to the mystery of the event.

The passengers discussed the sighting, and some claimed to have seen more details, though the witness was unsure if they were real or just misperceptions. There were no signs of an airbase in the area, and although he saw several planes, none were hidden. The man, a regular train traveler, found nothing unusual about the trip, but the experience left him with unanswered questions. Were those objects regular aircraft? Or something else entirely?
