When the train neared the Fairmount Avenue stop shortly after midnight on Thursday, the man reached out like an adoring parent and directed the 3- or 4-year-old tyke to an open seat.

Then he flew into a monstrous rage.

Without uttering a word, police said, the unidentified man whipped out a double-claw hammer and began bludgeoning a 20-year-old man who was dozing off in his seat.

For five long minutes, SEPTA surveillance cameras captured the deranged attacker - who was still on the loose late last night- digging his hammer into the man’s head and neck.

Through it all, disgusted investigators said, at least 10 passengers stood by and did nothing as the random attack moved from the train to the platform, when the hammer-wielding maniac tried to push his victim down onto the train tracks.

When the beating was finished and the suspect fled with the little boy, the victim staggered back onto the train, bloodied, confused and alone, said Detective Kenneth Roach, of Central Detectives.

And even then, no one tried to help him.

WTF Wednesday.
