When a train shoots sparks on the tracks.
Ejaculation of a train.

Person 1: OMG, did you see the sparks from that train?
Person 2: Yeah, that was some serious train jizz

jizz train 

a thin stream of seamen put somewhere on a girl's(most likely a skank's) body by someone she has had a sexual encounter with.

That skank let me leave a jizz train in her hair!

Choo Choo! hey ladies, wanna hop on my jizz train tonight?
