Long Shaped object that had lights underneath no sound looked almost like a train in the sky except only one section of train.

Long Shaped object that had lights underneath no sound could be heard at all. Was headed east then turned North east. Then the object begin to fade out or disappear from the font to the back until it was completely gone or invisible. This all happened in a matter of 2 to 3 minutes. Unfortunately I have no images of this event. It could have possibly been shaped like the image I uploaded but it had what appeared to be windows underneath. It was against a dark sky and all you could really see was the light from the windows underneath. These were not overly bright lights just amber looking lights but visible from the ground at night.
