The red spots

My mother told me during her childhood she moved with her family to new town which called Itay El Baroud and she lived in new house near to the railways tracks and in this time there is lights in the streets and they lived in the second floor
During the night she and her sister was watching red light spots comes from the land and run on the railway and disappear suddenly without reason for these spots so they can't move during the night to come out from their home.
My mother asked my grandmother about that she told her about that and she told her these spots for the people killed by train during their passing on the railway and these spots just their ghosts or their partners from Jinn.

Really i asked many person who lived near to the railway from long time when there is no lights in the streets and many people watched something like that.
